The journey of a thousand miles begins with one step.

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

Don’t practice until you get it right, practice until you can’t get it wrong.

Skills are built not born.

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

Success is not final, failure is not fatal.  It is the courage to continue that counts.

The temptation to quit will be the greatest when you are about to succeed

Pure mathematics is in its way, the poetry of logical ideas.

Procrastination is the thief of time and the enemy of success.

You're not in competition with anyone but yourself. Outdo your past, not other people.

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

Time is your friend, impulse is your enemy.

I can is 100 times more important than IQ.
