Success is not final and failure is not fatal. It is the courage to continue that counts.

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

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

We all have two lives. The second begins when we realise we only have one. 

Hard work - a two way street where you get exactly what you put in.

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

I think, therefore I am.

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Start, struggle, fail, fix and learn. Repeat.

Tough times never last, but tough people do.

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

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