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

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

Success can never happen without the journey (struggle).

You can be shown the path, but only you can make the first step.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

The easiest person to deceive is yourself.

You cannot escape the responsibility of tomorrow by evading it today

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

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.

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

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

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

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