What is it?

Terri Mak

It is powerful, but no one can fully utilise it.

It is complex, no one can fully understand it.

It is like a sponge, its absorbing ability can be unlimited if you know how to use it.

Each one of them is unique.

 

Where is it?

Every person carries it, but not every one uses it.

 

People use it, but could never use it to its optimal performance.

When used a lot, its performance will be increased.

If there is problem, no one can really fix it.

 

So what is it?
