Hard work - a two way street where you get exactly what you put in.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

It always seems impossible until it's done.

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

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

Success is not final and failure is not fatal. It is the courage to continue that counts.

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

Don’t hang your targets after you’re done shooting.

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

Your limitation - its only your imagination.
