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. 

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Failure is NOT your destiny. Failure is the key to success.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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

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

Success can never happen without the journey (struggle).

In order to become better than anybody else you must first become better than yourself.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Don’t be afraid to work hard and find out how good you can really be.

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

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

Tomorrow is worth more than yesterday but less than today.

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