Your time is limited, so don't waste it living som...

We want to reinvent the phone. What's the killer app? The killer app is making calls! It's amazing how hard it is to make calls on most phones. We want to let you use contacts like never before - sync your iPhone with your PC or mac.

Sometimes when you innovate, you make mistakes. It is best to admit them quickly, and get on with improving your other innovations.

No one wants to die. Even people who want to go to heaven don't want to die to get there. And yet death is the destination we all share. No one has ever escaped it. And that is as it should be, because Death is very likely the single best invention of Life. It is Life's change agent. It clears out the old to make way for the new.

I don't feel old. I don't feel anything till noon. That's when it's time for my nap.

It takes a long time to become young.

Growing old is no more than a bad habit which a busy person has no time to form.

Old age is an excellent time for outrage. My goal is to say or do at least one outrageous thing every week.

It is a blessed thing that in every age some one has had the individuality enough and courage enough to stand by his own convictions.

In fact, my courage and my bravery at a young age was the thing I was bullied for, a kind of 'Who do you think you are?'

Is he alone who has courage on his right hand and faith on his left hand?

Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young.

There is a fountain of youth: it is your mind, your talents, the creativity you bring to your life and the lives of people you love. When you learn to tap this source, you will truly have defeated age.

Life would be infinitely happier if we could only be born at the age of eighty and gradually approach eighteen.

Probably the happiest period in life most frequently is in middle age, when the eager passions of youth are cooled, and the infirmities of age not yet begun as we see that the shadows, which are at morning and evening so large, almost entirely disappear at midday.
