Procrastination makes easy things hard and hard things harder.

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

Success is a journey, not a destination.

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

Hard work beats talent when talent doesn't work hard.

There are no shortcuts to any place worth going.

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

Skills are built not born.

Failure to prepare = preparing to fail

The greatest glory in loving lies not in never falling, but in rising every time we fall.

The greatest mistake we make is living in constant fear that we will make one.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Tough times never last, but tough people do.

The bad news is time flies, the good new is that you're the pilot.

The temptation to quit will be the greatest when you are about to succeed
