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

99% of failures come from people who have the habit of making excuses.

Don’t hang your targets after you’re done shooting.

It is never too late to become what you might have been

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

Failure is NOT your destiny. Failure is the key to success.

Knowledge is of no value unless you put it into practice.

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

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

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

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

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

Procrastination is the thief of time and the enemy of success.

Tomorrow is worth more than yesterday but less than today.
