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. 

Success can never happen without the journey (struggle).

Nobody said it’d be easy, they just promised it would be worth it.

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

The easiest person to deceive is yourself.

Failure is not the opposite of success, it is part of the success.

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

Your limitation - its only your imagination.

You can have results or excuses, not both

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

Just stick with it, what seems hard now will one day be your warm up.

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

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

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