There is no elevator to success, you have to take the stairs.

Never underestimate the importance of small steps. small steps = big changes. 

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

I can is 100 times more important than IQ.

You cannot escape the responsibility of tomorrow by evading it today

Instead of finding reasons why you can't, find reasons why you can.

Success is a journey, not a destination.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

Failure to prepare = preparing to fail

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

Patience is when you’re supposed to get mad, but you choose to understand

It always seems impossible until it's done.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Just stick with it, what seems hard now will one day be your warm up.
