The greatest enemy to human potential is your comfort zone

Fall down seven times, stand up eight.

Skills are built not born.

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

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

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

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

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

The journey of a thousand miles begins with one step.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

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

A hero is no braver than an ordinary man, but he is braver five minutes longer.
