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

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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

The wise person knows that no answer is also an answer

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

You cannot start the next chapter of your life if you keep re-reading the last 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. 

The easiest person to deceive is yourself.

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

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

I think, therefore I am.

Hope might be a good breakfast, but it makes a very poor dinner

Your attitude is everything. Pick a good one.

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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.
