I can is 100 times more important than IQ.

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

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

Never underestimate the importance of small steps. small steps = big changes. 

Tough times never last, but tough people do.

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

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

It is never too late to turn an unproductive day into a productive one.

Everything you want is on the other side of fear

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

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

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

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.

Try and do one thing each day that you would really rather not do.
