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

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. 

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

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

Failure to prepare = preparing to fail

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

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

The wise person knows that no answer is also an answer

Success is a journey, not a destination.

Skills are built not born.

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

Lose an hour in the morning and you will spend all day looking for it.

Instead of finding reasons why you can't, find reasons why you can.
