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. 

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

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

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

The wise person knows that no answer is also an answer

Everything you want is on the other side of fear

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

Dreams don't work unless you do.

FAIL - First Attempt In Learning

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

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

Procrastination makes easy things hard and hard things harder.

Don’t hang your targets after you’re done shooting.

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

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there
