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 compare yourself to others. Compare yourself to the person you were yesterday.

99% of genius comes from hard work, the remaining 1% comes from innate talent

If you fail, next time fail better.

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

He who has begun his task is half-way done. Have the courage to begin!

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

If you can understand just one thing thoroughly, then you will understand everything.

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

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

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

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

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

The bad news is time flies, the good new is that you're the pilot.
