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

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

You can hire a tutor but you can't hire someone to practice for you.

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.

There are no bad mistakes in maths, only discoveries.

Fall down seven times, stand up eight.

You can have results or excuses, not both

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

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

You cannot escape the responsibility of tomorrow by evading it today

You cannot start the next chapter of your life if you keep re-reading the last one.

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

He who has begun his task is half-way done. Have the courage to begin!

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.

The wise person knows that no answer is also an answer
