Don’t practice until you get it right, practice until you can’t get it wrong.

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

Success can never happen without the journey (struggle).

You cannot start the next chapter of your life if you keep re-reading the last one.

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

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

There are no shortcuts to any place worth going.

Success is the sum of small repeated efforts, day in and day out.

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

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

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. 

We learn more from failure than we do from success.

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.

Lose an hour in the morning and you will spend all day looking for it.

Don't fear failure, fear being in the same exact same place next year as you are now.
