Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

Time is your friend, impulse is your enemy.

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

Just stick with it, what seems hard now will one day be your warm up.

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. 

The greatest enemy to human potential is your comfort zone

Tough times never last, but tough people do.

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

You cannot escape the responsibility of tomorrow by evading it today

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Everything you want is on the other side of fear

We learn more from failure than we do from success.

Fall down seven times, stand up eight.

I can is 100 times more important than IQ.
