Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

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

Tough times never last, but tough people do.

The easiest person to deceive is yourself.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

There are no bad mistakes in maths, only discoveries.

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

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

Patience is when you’re supposed to get mad, but you choose to understand

You cannot escape the responsibility of tomorrow by evading it today

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

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

If you want to succeed, double your failure rate.
