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

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

Shoot for the moon and even if you miss you’ll land among the stars/

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

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

You cannot escape the responsibility of tomorrow by evading it today

Don’t practice until you get it right, practice until you can’t get it wrong.

Start, struggle, fail, fix and learn. Repeat.

The journey of a thousand miles begins with one step. 

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

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Success can never happen without the journey (struggle).

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