Don’t be afraid to work hard and find out how good you can really be.

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

If you fail, next time fail better.

You're not in competition with anyone but yourself. Outdo your past, not other people.

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

It doesn’t matter where you start, it matters how you end

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Your attitude is everything. Pick a good one.

Failure to prepare = preparing to fail

Dreams don't work unless you do.

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

We all make mistakes. What matters is how we choose to move forwards from them.

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

The journey of a thousand miles begins with one step. 

We learn more from failure than we do from success.
