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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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

If you fail, next time fail better.

We all have two lives. The second begins when we realise we only have one. 

Your limitation - its only your imagination.

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

Your attitude is everything. Pick a good one.

We all make mistakes. What matters is how we choose to move forwards from them.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Life is full of opportunities. With every opportunity that is missed, another one is born.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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

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

Never underestimate the importance of small steps. small steps = big changes.
