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

Pure mathematics is in its way, the poetry of logical ideas.

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

The journey of a thousand miles begins with one step.

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

He who has begun his task is half-way done. Have the courage to begin!

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

We learn more from failure than we do from success.

Don’t be afraid to work hard and find out how good you can really be.

Skills are built not born.

Go as far as you can see, when you get there, you’ll be able to see further

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

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

Instead of finding reasons why you can't, find reasons why you can.

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