Time is your friend, impulse is your enemy.

Dreams don't work unless you do.

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

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Skills are built not born.

Tough times never last, but tough people do.

The road to success is like a staircase. If you want to succeed, double your failure rate

Everything you want is on the other side of fear

I think, therefore I am.

Success is a journey, not a destination.

I have not failed, I've just found 10,000 ways that won't work.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Knowledge is of no value unless you put it into practice.

We learn more from failure than we do from success.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.
