Jealousy is the fear of comparison.

He who seeks rest finds boredom. He who seeks work finds rest.

To expect the unexpected shows a thoroughly modern intellect.

Success is not measured by what you accomplish, but by the opposition you have encountered, and the courage with which you have maintained the struggle against overwhelming odds.

Word of mouth is the best medium of all.

Be at war with your vices, at peace with your neighbors, and let every new year find you a better man.

The work of the individual still remains the spark that moves mankind ahead even more than teamwork.

If you're bored with life - you don't get up every morning with a burning desire to do things - you don't have enough goals.

If a window of opportunity appears, don't pull down the shade.

Man is equally incapable of seeing the nothingness from which he emerges and the infinity in which he is engulfed.

We are what we believe we are.

The final test of a leader is that he leaves behind him in other men the conviction and the will to carry on.

You cry and you scream and you stomp your feet and you shout. You say, 'You know what? I'm giving up, I don't care.' And then you go to bed and you wake up and it's a brand new day, and you pick yourself back up again.

Success depends upon previous preparation, and without such preparation there is sure to be failure.

What worries you, masters you.

I come from a family where gravy is considered a beverage.

Do not say, 'It is morning,' and dismiss it with a name of yesterday. See it for the first time as a newborn child that has no name.

Nothing will work unless you do.

All of us every single year, we're a different person. I don't think we're the same person all our lives.

Everyone has highs and lows that they have to learn from, but every morning I start off with a good head on my shoulders, saying to myself, 'It's going to be a good day!'.

Happiness lies in the joy of achievement and the thrill of creative effort.

Don't stay in bed, unless you can make money in bed.

Accept what people offer. Drink their milkshakes. Take their love.

So long as you have food in your mouth, you have solved all questions for the time being.
