Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

Knowledge is of no value unless you put it into practice.

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

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

Try and do one thing each day that you would really rather not do.

A book a day keeps the stupidity away.

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. 

Success is a journey, not a destination.

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

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

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

Fall down seven times, stand up eight.

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

Run in the morning before your body figures out what you're doing
