The greatest mistake we make is living in constant fear that we will make one.

Failure to prepare = preparing to fail

You can have results or excuses, not both

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. 

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

The road to success is like a staircase. If you want to succeed, double your failure rate

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

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

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Never underestimate the importance of small steps. small steps = big changes. 

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

There are no shortcuts to any place worth going.

Success is the sum of small repeated efforts, day in and day out.

Procrastination is the thief of time and the enemy of success.

The bad news is time flies, the good new is that you're the pilot.
