Sometime I do wonder, why am I that stupid to give my time and effort away just to help people achieving success in their studies.

For sure I help because they are my friends, or I will definitely ask for a price.
I like to see their joy when I get things done.
It is an invaluable feedback to keep me going.

But to be a more practical person, I must have something solid to make this worthwhile.

So I started to look at this matter closer.
I tried to search for solid value which I can derive from it.

Then, I realized that I tend to be faster in understanding a problem.
I am more open to new challenge and new problem.

The database that stores the solution for problem has been piled up in my head.
I have more ways to solve a problem which I can pick the best one from it.

I gained knowledge on various fields, various languages, various platforms.
I implemented new programming technique and became familiar with it.
I can code in the same speed as my typing.

It all made sense to me now.

There are things which you can't put a figure on it.
When the time is right, these will sum up to be a big one.
