The temptation to quit will be the greatest when you are about to succeed

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

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

Dreams don't work unless you do.

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

It always seems impossible until it's done.

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

Skills are built not born.

Time is your friend, impulse is your enemy.

Shoot for the moon and even if you miss you’ll land among the stars/

There are no shortcuts to any place worth going.

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. 

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

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