It always seems impossible until it's done.

Mistakes have the power to turn you into something better than you were before.

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

Your attitude is everything. Pick a good one.

I think, therefore I am.

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

Your limitation - its only your imagination.

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

Hard work beats talent when talent doesn't work hard.

Fall down seven times, stand up eight.

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

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

A book a day keeps the stupidity away.

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. 

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