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

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

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

The bad news is time flies, the good new is that you're the pilot.

Skills are built not born.

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

Success is a journey, not a destination.

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

Fall down seven times, stand up eight.

Dreams don't work unless you do.

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

It always seems impossible until it's done.

Failure to prepare = preparing to fail

99% of failures come from people who have the habit of making excuses.
