Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

Failure is not the opposite of success, it is part of the success.

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

There are no bad mistakes in maths, only discoveries.

The road to success is like a staircase. If you want to succeed, double your failure rate

Everything you want is on the other side of fear

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

I think, therefore I am.

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

A book a day keeps the stupidity away.

Success is a journey, not a destination.

No one starts out on top. You have to work your way up.

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

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

It is never too late to turn an unproductive day into a productive one.
