There are no shortcuts to any place worth going.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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. 

I can is 100 times more important than IQ.

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.

Failure to prepare = preparing to fail

Pure mathematics is in its way, the poetry of logical ideas.

Hard work beats talent when talent doesn't work hard.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

You're not in competition with anyone but yourself. Outdo your past, not other people.

We learn more from failure than we do from success.

Your limitation - its only your imagination.

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

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

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