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

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

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

Procrastination makes easy things hard and hard things harder.

If you want to succeed, double your failure rate.

Failure to prepare = preparing to fail

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

Instead of finding reasons why you can't, find reasons why you can.

Tomorrow is worth more than yesterday but less than today.

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.

Run in the morning before your body figures out what you're doing

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 enemy to human potential is your comfort zone

Success can never happen without the journey (struggle).

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.
