Fall down seven times, stand up eight.

There are no shortcuts to any place worth going.

Procrastination makes easy things hard and hard things harder.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Everything you want is on the other side of fear

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

The greatest glory in loving lies not in never falling, but in rising every time we fall.

The master has failed more times than the beginner has even tried

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

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. 

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

Time is your friend, impulse is your enemy.

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

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