Life is about exchanging something for another.

My principal is always simple.

It's always about gain/invested resources.

How much happiness I can generate by investing this amount of resource into it?
Do I have a better alternative?

Living 22 years in this world has taught me one thing.
Money is not the root of evil.

People who don't see it simply don't understand the game rule.

Whether you have realized or not, all of us have unintentionally involved in kind of trade.

We sell our energy and time to buy money and when we have money, we sell our money to buy others' energy and time.

It's not about who can earn more money in this world.
It's about who can make the highest gain in the exchange.

How much money you can earn per time per energy invested?
How much time and energy you can buy per money invested?

The ultimate goal of life is not about how much money you have.
It's about how much time and energy you can work out for yourself.

You spend 10 minutes to buy RM 20, and if you have really looked into it, you can actually use the RM 20 to buy 20 minutes.
And your 10 minutes have then earn back 10 minutes for yourself.

If you keep repeating this cycle, you will start realizing that you have more and more personal time to be spent for yourself and the one you loved.

Money is not the root of evil.
It provides a medium for you to earn more time and energy back.

This is my very personal theorem of life.
I'm still experimenting it.
