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

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

Time is your friend, impulse is your enemy.

We learn more from failure than we do from success.

Hope might be a good breakfast, but it makes a very poor dinner

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.

You can hire a tutor but you can't hire someone to practice for you.

Try and do one thing each day that you would really rather not do.

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

It always seems impossible until it's done.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Fall down seven times, stand up eight.
