Technology

You're about to embark on careers that will take many of you to companies not yet founded, using devices not yet developed, based on ideas not yet conceived. That is how fast things are moving.

The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it.

As you get older, you realize that no one has all the answers. It turns out that life is an exercise in living with the certainty of uncertainty.

It's okay to not really know what you're doing, and just trust your gut. Make the best judgment you can. There's not going to be a syllabus assigned to you.

You're all here because you're good at not failing. This is the culmination of doing a great job at not failing. However, there are no GPAs after this. Failure is an option.

The more distracted we become, and the more emphasis we put on speed at the expense of depth, the less able we are to care.

It's easier to friend someone than to be someone's friend. It's easier to like things than to love them. It's easier to say nothing — but people who become used to saying nothing become used to being nobody.

The happiest and most successful people I know don't just love what they do, they're obsessed with solving an important problem, something that matters to them. They remind me of a dog chasing a tennis ball.

The positive revolutions are not going to be caused by generals and politicians. They are going to be caused by innovators like you.

You get some success. You run into some walls. And it's how tenacious you are, how irrepressible, how ultimately optimistic and tenacious you are about it that will determine your success.

For the most important decisions in your life, trust your intuition, and then work with everything you have, to prove it right.

Without the possibility of failure, there is no possibility of success.
