I think, therefore I am.

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

We are all maths people : step 1 - do maths and step 2 - be a person. 

The greatest enemy to human potential is your comfort zone

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. 

Fall down seven times, stand up eight.

No one starts out on top. You have to work your way up.

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.

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

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

It is never too late to turn an unproductive day into a productive one.

The temptation to quit will be the greatest when you are about to succeed

Failure to prepare = preparing to fail

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

Just stick with it, what seems hard now will one day be your warm up.
