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

Time is your friend, impulse is your enemy.

It doesn’t matter where you start, it matters how you end

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

Fall down seven times, stand up eight.

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

Procrastination makes easy things hard and hard things harder.

"I" not them. Be the best version of you.

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

Everything you want is on the other side of fear

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

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

Skills are built not born.

We all have two lives. The second begins when we realise we only have one. 

If you fail, next time fail better.
