Just stick with it, what seems hard now will one day be your warm up.

Skills are built not born.

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

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

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

The easiest person to deceive is yourself.

Practice like you’ve never won. Perform like you’ve never lost.

Failure is NOT your destiny. Failure is the key to success.

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

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

I think, therefore I am.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

It always seems impossible until it's done.

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

The power of reflection is the most powerful skill you’ll learn.
