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. 

I think, therefore I am.

I have not failed, I've just found 10,000 ways that won't work.

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

Tough times never last, but tough people do.

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

We learn more from failure than we do from success.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

It is never too late to become what you might have been

We all have two lives. The second begins when we realise we only have one. 

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

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

Practice like you’ve never won. Perform like you’ve never lost.

You're not in competition with anyone but yourself. Outdo your past, not other people.
