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

I think, therefore I am.

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

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

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. 

It is never too late to become what you might have been

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

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

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

Your attitude is everything. Pick a good one.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

We learn more from failure than we do from success.

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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