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

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

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

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

The journey of a thousand miles begins with one step. 

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

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

You can have results or excuses, not both

Success is a journey, not a destination.

Failure is not the opposite of success, it is part of the success.

Tomorrow is worth more than yesterday but less than today.

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

You cannot start the next chapter of your life if you keep re-reading the last one.

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.

I think, therefore I am.
