The greatest enemy to human potential is your comfort zone

I think, therefore I am.

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

"I" not them. Be the best version of you.

The journey of a thousand miles begins with one step. 

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

It is never too late to become what you might have been

Your attitude is everything. Pick a good one.

Tough times never last, but tough people do.

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

Fall down seven times, stand up eight.

There are no bad mistakes in maths, only discoveries.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

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.
