You can have results or excuses, not both

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

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 fear failure, fear being in the same exact same place next year as you are now.

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

I think, therefore I am.

The master has failed more times than the beginner has even tried

Dreams don't work unless you do.

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

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

Mistakes have the power to turn you into something better than you were before.

The wise person knows that no answer is also an answer

Start, struggle, fail, fix and learn. Repeat.

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

Our fixed mindset builds our cage, fear keeps us in it.
