Can You Guess?

Sometimes it makes you sad, but sometimes makes you happy.
Sometimes it makes you bored, but sometimes makes you very excited.
It builds your exultation, but also can destroy it.
You search for it when you lose it, but when you have it, you hardly ever regard it.
It can make you crazy and it can turn something impossible to be possible.
But the true form of it is how we regard it as we regard ourselves.
We are here because of it and God always gives it to us.
