Time is your friend, impulse is your enemy.

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

Success is a journey, not a destination.

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

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

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.

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

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

Tough times never last, but tough people do.

99% of genius comes from hard work, the remaining 1% comes from innate talent

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

No one starts out on top. You have to work your way up.

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

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.
