Fall down seven times, stand up eight.

There are no shortcuts to any place worth going.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

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

I think, therefore I am.

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

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

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

If you want to succeed, double your failure rate.

Failure to prepare = preparing to fail

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

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