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

I think, therefore I am.

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

Dreams don't work unless you do.

Run in the morning before your body figures out what you're doing

You can hire a tutor but you can't hire someone to practice for you.

Tough times never last, but tough people do.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

The bad news is time flies, the good new is that you're the pilot.

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

Success is the sum of small repeated efforts, day in and day out.

The journey of a thousand miles begins with one step.
