There are no bad mistakes in maths, only discoveries.

The greatest mistake we make is living in constant fear that we will make one.

Failure to prepare = preparing to fail

We learn more from failure than we do from success.

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.

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

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

Procrastination makes easy things hard and hard things harder.

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. 

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

Dreams don't work unless you do.

Fall down seven times, stand up eight.

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

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