The master has failed more times than the beginner has even tried

Hard work beats talent when talent doesn't work hard.

The power of reflection is the most powerful skill you’ll learn.

If you want to succeed, double your failure rate.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

Don't fear failure, fear being in the same exact same place next year as you are now.

The easiest person to deceive is yourself.

FAIL - First Attempt In Learning

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

It always seems impossible until it's done.

The greatest enemy to human potential is your comfort zone

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

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

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