There are no bad mistakes in maths, only discoveries.

The easiest person to deceive is yourself.

You can have results or excuses, not both

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

You cannot escape the responsibility of tomorrow by evading it today

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Don’t hang your targets after you’re done shooting.

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

Mistakes have the power to turn you into something better than you were before.

FAIL - First Attempt In Learning

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.
