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

There are no bad mistakes in maths, only discoveries.

If you can understand just one thing thoroughly, then you will understand everything.

It always seems impossible until it's done.

The journey of a thousand miles begins with one step. 

Failure is not the opposite of success, it is part of the success.

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

99% of genius comes from hard work, the remaining 1% comes from innate talent

If you want to succeed, double your failure rate.

A book a day keeps the stupidity away.

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

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

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

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

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