It always seems impossible until it's done.

Procrastination makes easy things hard and hard things harder.

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

Tough times never last, but tough people do.

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

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

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

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

We learn more from failure than we do from success.

There are no bad mistakes in maths, only discoveries.

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.

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

Patience is when you’re supposed to get mad, but you choose to understand

Tomorrow is worth more than yesterday but less than today.
