If you want to succeed, double your failure rate.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

Instead of finding reasons why you can't, find reasons why you can.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

The greatest mistake we make is living in constant fear that we will make one.

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

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

The power of reflection is the most powerful skill you’ll learn.

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. 

Success can never happen without the journey (struggle).

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

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

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.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.
