Don’t be afraid to work hard and find out how good you can really be.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

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

It always seems impossible until it's done.

It is never too late to become what you might have been

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

Dreams don't work unless you do.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Tomorrow is worth more than yesterday but less than today.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

It doesn’t matter where you start, it matters how you end

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

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