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

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

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

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

You cannot escape the responsibility of tomorrow by evading it today

Knowledge is of no value unless you put it into practice.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.
