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

I think, therefore I am.

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

Don’t practice until you get it right, practice until you can’t get it wrong.

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.

If you fail, next time fail better.

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