What is life ?

*Life is like a puzzle.*

You don't always know how the picture will end up looking like at the end.
The pieces are scattered and every one is individual.
There are the easy parts and the hard parts.
You're going to get frustrated. Sometimes you should just take a break.
You try to learn from your mistakes so as not to repeat yourself-- which you sometimes still do anyway.
Always keep trying. You never know when you're going to get lucky.
