When you make a mistake, take another chance. Only when you choose not to do so do you fail.

You cannot start the next chapter of your life if you keep re-reading the last one.

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

If you fail, next time fail better.

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

You can have results or excuses, not both

It always seems impossible until it's done.

The temptation to quit will be the greatest when you are about to succeed

Success is the sum of small repeated efforts, day in and day out.

You can be shown the path, but only you can make the first step.

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

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.

The greatest mistake we make is living in constant fear that we will make one.

We learn more from failure than we do from success.

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.
