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. 

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

Success is not final and failure is not fatal. It is the courage to continue that counts.

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

"I" not them. Be the best version of you.

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

The journey of a thousand miles begins with one step. 

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

Procrastination is the thief of time and the enemy of success.

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

If you want to succeed, double your failure rate.

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

You're not in competition with anyone but yourself. Outdo your past, not other people.

The easiest person to deceive is yourself.
