Everything you want is on the other side of fear

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. 

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

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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.

Procrastination makes easy things hard and hard things harder.

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

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

A book a day keeps the stupidity away.

The easiest person to deceive is yourself.

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