The easiest person to deceive is yourself.

A book a day keeps the stupidity away.

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

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

Tomorrow is worth more than yesterday but less than today.

Success is not final, failure is not fatal.  It is the courage to continue that counts.

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

Skills are built not born.

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

We are all maths people : step 1 - do maths and step 2 - be a person. 

If you can understand just one thing thoroughly, then you will understand everything.

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

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

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.

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