Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

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

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

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

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

Run in the morning before your body figures out what you're doing

It always seems impossible until it's done.

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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

It doesn’t matter where you start, it matters how you end

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

The master has failed more times than the beginner has even tried
