Success can never happen without the journey (struggle).

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

Nobody said it’d be easy, they just promised it would be worth it.

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

Fall down seven times, stand up eight.

Failure to prepare = preparing to fail

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

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

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

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

If you fail, next time fail better.

Failure is NOT your destiny. Failure is the key to success.

It always seems impossible until it's done.

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.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.
