Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

We learn more from failure than we do from success.

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.

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

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. 

Never underestimate the importance of small steps. small steps = big changes. 

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

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

Skills are built not born.

Knowledge is of no value unless you put it into practice.

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

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Procrastination is the thief of time and the enemy of success.

Failure to prepare = preparing to fail
