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. 

Everything you want is on the other side of fear

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

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

We all have two lives. The second begins when we realise we only have one. 

Tough times never last, but tough people do.

Nobody said it’d be easy, they just promised it would be worth it.

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

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

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

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

Procrastination makes easy things hard and hard things harder.

No one starts out on top. You have to work your way up.

The easiest person to deceive is yourself.
