Nothing is impossible if you want it badly enough. Impossible = I'm possible.

There are no shortcuts to any place worth going.

You cannot escape the responsibility of tomorrow by evading it today

No one starts out on top. You have to work your way up.

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.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

It always seems impossible until it's done.

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

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

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

There are no bad mistakes in maths, only discoveries.

If you can understand just one thing thoroughly, then you will understand everything.
