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

The journey of a thousand miles begins with one step. 

Do what you have always done and you will always be what you have always been

The greatest enemy to human potential is your comfort zone

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

I can is 100 times more important than IQ.

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).

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