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. 

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

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

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

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

Success is the sum of small repeated efforts, day in and day out.

The easiest person to deceive is yourself.

I have not failed, I've just found 10,000 ways that won't work.

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

You can have results or excuses, not both

It always seems impossible until it's done.

If you fail, next time fail better.

Shoot for the moon and even if you miss you’ll land among the stars/

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

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