A book a day keeps the stupidity away.

Skills are built not born.

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. 

Everything you want is on the other side of fear

Success is a journey, not a destination.

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.

I can is 100 times more important than IQ.

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

There are no bad mistakes in maths, only discoveries.

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

The greatest enemy to human potential is your comfort zone

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.

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

There is no elevator to success, you have to take the stairs.

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