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

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

Shoot for the moon and even if you miss you’ll land among the stars/

There are no bad mistakes in maths, only discoveries.

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

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

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Procrastination makes easy things hard and hard things harder.

Your attitude is everything. Pick a good one.

There is no elevator to success, you have to take the stairs.

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

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Everything that happens was once a dream.
