We all have two lives. The second begins when we realise we only have one. 

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

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

You cannot escape the responsibility of tomorrow by evading it today

You can have results or excuses, not both

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

There are no bad mistakes in maths, only discoveries.

Try and do one thing each day that you would really rather not do.

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. 

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

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

The wise person knows that no answer is also an answer

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