Don’t practice until you get it right, practice until you can’t get it wrong.

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

Lose an hour in the morning and you will spend all day looking for it.

The wise person knows that no answer is also an answer

It always seems impossible until it's done.

Tomorrow is worth more than yesterday but less than today.

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

Don't fear failure, fear being in the same exact same place next year as you are now.

You can have results or excuses, not both

Dreams don't work unless you do.

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

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

Pure mathematics is in its way, the poetry of logical ideas.

Failure to prepare = preparing to fail

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.
