I think, therefore I am.

There is no elevator to success, you have to take the stairs.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

You cannot escape the responsibility of tomorrow by evading it today

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

We all make mistakes. What matters is how we choose to move forwards from them.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

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 journey of a thousand miles begins with one step.

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

We learn more from failure than we do from success.

Practice like you’ve never won. Perform like you’ve never lost.
