If you fail, next time fail better.

I think, therefore I am.

There are no shortcuts to any place worth going.

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

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

The easiest person to deceive is yourself.

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

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

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

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.

Success can never happen without the journey (struggle).

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Patience is when you’re supposed to get mad, but you choose to understand

Dreams don't work unless you do.
