The temptation to quit will be the greatest when you are about to succeed

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

The wise person knows that no answer is also an answer

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

Tough times never last, but tough people do.

We learn more from failure than we do from success.

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.

A book a day keeps the stupidity away.

It is never too late to become what you might have been

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

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

Mistakes have the power to turn you into something better than you were before.

If you want to succeed, double your failure rate.

The greatest mistake we make is living in constant fear that we will make one.

Your attitude is everything. Pick a good one.
