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

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

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

Success can never happen without the journey (struggle).

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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

Tough times never last, but tough people do.

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

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

Tomorrow is worth more than yesterday but less than today.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

Failure is NOT your destiny. Failure is the key to success.

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

If you fail, next time fail better.
