I think, therefore I am.

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. 

Time is your friend, impulse is your enemy.

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

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

You cannot escape the responsibility of tomorrow by evading it today

Skills are built not born.

Tough times never last, but tough people do.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Patience is when you’re supposed to get mad, but you choose to understand

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

Do what you have always done and you will always be what you have always been

Start, struggle, fail, fix and learn. Repeat.

Life is full of opportunities. With every opportunity that is missed, another one is born.

If you want to succeed, double your failure rate.
