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

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

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

If you fail, next time fail better.

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

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.

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. 

Hope might be a good breakfast, but it makes a very poor dinner

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

You can hire a tutor but you can't hire someone to practice for you.

A book a day keeps the stupidity away.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

Tough times never last, but tough people do.

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time.
