Fall down seven times, stand up eight.

Dreams don't work unless you do.

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. 

We learn more from failure than we do from success.

The greatest mistake we make is living in constant fear that we will make one.

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

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

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

Don't fear failure, fear being in the same exact same place next year as you are now.

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

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

99% of genius comes from hard work, the remaining 1% comes from innate talent

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.
