There are no bad mistakes in maths, only discoveries.

We learn more from failure than we do from success.

The road to success is like a staircase. If you want to succeed, double your failure rate

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Go as far as you can see, when you get there, you’ll be able to see further

Failure to prepare = preparing to fail

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Tomorrow is worth more than yesterday but less than today.

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

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. 

Your limitation - its only your imagination.

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