Fall down seven times, stand up eight.

If you want to succeed, double your failure rate.

It always seems impossible until it's done.

Instead of finding reasons why you can't, find reasons why you can.

Skills are built not born.

The journey of a thousand miles begins with one step. 

Pure mathematics is in its way, the poetry of logical ideas.

There are no bad mistakes in maths, only discoveries.

There is no elevator to success, you have to take the stairs.

Failure to prepare = preparing to fail

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

Knowledge is of no value unless you put it into practice.

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

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

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