Onward To Success

Life is not without struggles.  There are circumstances that test our determination to succeed. We may fail along the way, maybe several times but it doesn’t matter.  We get up, learn from our failures and go on to realize our dream. And I would say, dream big. It should be big enough to inspire us each day.

I’d like to share 3 things we need on our journey to success.

1. Don’t stop learning.
With the recent advances in information technology,  vast resources are made available to us. So learn as much as you can and acquire new skills. Do a self-study on any new available technologies or topics that interest you if there are no opportunities for formal training. That would give you a significant advantage over others even those foreign counterparts you may have in your career life.  And never forget to learn from the people around you.

2. Don’t be afraid to take risk.
Trying to do something you haven’t yet tried involves risk. And generally, we are afraid to take risk. We are so afraid to fail. But if we look at the people we consider successful, they have their share of failures.

3. Go beyond your comfort zone.
We have a tendency to stay within our comfort zone. But I would say more exciting challenges are out there. The more rewarding thing to experience is to overcome challenges and discover new things. At first, we’ll feel the stress and discomfort but the success at the end will be much sweeter.

So if you don’t stop learning, never afraid of taking risk and willing  to go beyond your comfort zone, then you would surely be amazed at the success you would achieve. And above all, honor God and trust in Him for it is HE who gives us the ability to produce wealth (Deuteronomy 8:18).

The Most Important Decision

Where is your destination?

 

What to do when your car A/C blower stops working?

When your car aircon blower stops working on lower speeds (commonly speed “1”), then the most likely culprit is the blower motor resistor. Usually when you have resistor damage, the blower would still work on the highest speed (“4”).  The figure below shows the typical blower motor resistor diagram.

Typical Resistor Diagram

So when your car A/C blower stops working, there’s a quick fix to make it working again. And you don’t need to spend money or go to the auto repair shop when you can do it yourself easily.

Here is what I did and the blower is still working for more than a year now.  First, I needed to locate the resistor.  The usual location is near the blower motor behind the glovebox in the front passenger seat. Second, I removed the glovebox and then the resistor. Third, I checked for broken wire coil connections and joined them by twisting the wire ends together.  And finally, I put back the resistor and the A/C was up and blowing cold air on all speed settings!

Valedictory Address (MSU-IIT Class ’99)

(The Valedictory Address delivered during the 29th Commencement Exercises of Mindanao State University – Iligan Institute of Technology  on March 29, 1999).

Our esteemed guest speaker Hon. Secretary Benjamin E. Diokno, Hon. MSU President Diamael M. Lucman, Hon. Chancellor Camar A. Umpa, honorable MSU officials, deans and directors of various MSU-IIT units, faculty and staff of this Institute, fellow graduates, parents, visitors, my brethren in the Lord, ladies and gentlemen, good morning.

The most awaited occasion has finally come. This could be a day of mixed emotions for all of us. It is truly a great honor and pleasure for me to speak before this great crowd of intellectuals. It is an unspeakable joy!

I could hardly believe that I have successfully climbed the ladder of academic success. Since my early years, adversity has never been a foreign experience for me. I do not belong to a well-to-do family who can assure me of an adequate financial support needed for my schooling. In fact, I finished my high school education with the aid of a scholarship which I found very insufficient still. There were times that I only had a snack during lunch time just to reserve some of the money for my school expenses. At other times, water was enough. It was really hard. I understood that my parent’s income as a farmer would not be able to take me to college. But I did not give up. The difficulties that I went through had strongly motivated me all the more to approach life with great diligence and determination. By the grace of God, I satisfactorily passed the MSU-SASE and joined the College of Engineering of this Institute.

However, the hard times did not end there. During my 2nd year in college, a tragedy struck my whole family and left us in great emotional and economic crises. My father died and I took the responsibility of being the breadwinner. I was at the point of deciding to stop my study because the stipend that I regularly received from the Institute could not adequately meet the needs of my family. But God significantly used my friends, teachers and brethren in the Lord to encourage me to continue my study. Seeing that I was in need, the Lord faithfully blessed me with a scholarship from DOST-JLAP. As a steward of the resources God has given me, I budgeted wisely the monthly stipend I was receiving to support the family as well as my study.

With all the hardships and darkness that I experienced in life, God has given me the light of victory. As the ancient king of Israel said: “I lift up my eyes to the hills. Where does my help come from? My help comes from the Lord, Maker of heaven and earth.” Fellow graduates, remember the words of Ty Boyd which says: Things turn out best for people who make the best of the way things turn out. Life is really a struggle. The life I have lived is a life seasoned with painful trials and limitations. But it’s really true that God always brings good out of the negative circumstances in life. Difficulties can turn into tremendous blessings. We just have to learn to put our trust in God. I remember my former mentor told me, “When the going gets rough, never ever quit.”

This day, I suppose, is a memorable and triumphant celebration for most of us. But let us not be so overwhelmed and be deceived that success is merely measured by the degree and honors a person achieves in life. For me, what you call success is not a real success if there still exists turmoil within your inner being. Can you call those world-renowned personalities who committed suicide successful? Surely the famous French mathematician and philosopher Blaise Pascal is right when he said: We have a God-shaped vacuum in our hearts which only God can fill. In pursuing our dreams in life, let us not repeat the mistake of seeking fulfillment in material things. Man is not just a physical or intellectual being but a spiritual being as well. We must not fail to acknowledge that we have a great Creator, the all-knowing architect and designer of our life.

As this Commencement Exercises marks the beginning of our journey into the world of uncertainties, let’s always be reminded that we need Someone who knows everything and has walked the jungles of life ahead of us. He has a marvelous way of taking care of the uncertainties ahead. There is no such secret formula I found other than walking in His perfect guidance. You’ve got to know Him. He is Jesus – my Savior and King. So take up the challenge and ponder on this fundamental question: Why am I here in this physical world?

To our dear teachers, a thankful heart now bids a tearful farewell. Your patience and love in giving us unselfishly the intellectual knowledge has greatly equipped our young minds.

To our beloved parents, this is what we have become because of your sacrifices in supporting us.

A Place for Bikers

When you are into biking (mountain bike or road bike), then there is a place for you that I would recommend. This place I’m talking about is in Nuvali, Sta. Rosa City.

The old Marcos Mansion (Twin Mansion) is also near the area. And don’t miss to have a taste of the refreshing young coconut (buko).

If you want to experience the biking trail, you can go through the Bird Sanctuary area. One popular stopover for mountain bikers going on this trail is the so-called “biker’s cafe”.

And there’s also the place for wakeboarders (Republic Wakepark) and for golfers (Canlubang Golf & Country Club).
