There is no elevator to success, you have to take the stairs.

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

You can have results or excuses, not both

Go as far as you can see, when you get there, you’ll be able to see further

It always seems impossible until it's done.

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

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

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

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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. 

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