Apologies are not pass/fail.

Never lose the child-like wonder. It’s just too important. It’s what drives us. Help others.

I understand the arguments about how the billions of dollars spent to put men on the moon could have been used to fight poverty and hunger on Earth. But, look, I'm a scientist who sees inspiration as the ultimate tool for doing good. When you use money to fight poverty, it can be of great value, but too often, you're working at the margins. When you're putting people on the moon, you're inspiring all of us to achieve the maximum of human potential, which is how our greatest problems will eventually be solved. Give yourself permission to dream.

Experience is what you get when you didn't get what you wanted.

Randy Pausch on time management: Here's what I know: Time must be explicitly managed, like money. You can always change your plan, but only if you have one. Ask yourself: Are you spending your time on the right things? Develop a good filing system. Rethink the telephone. Delegate. Take a time out. Time is all you have. And you may find one day that you have less than you think.

Find the best in everybody. Just keep waiting no matter how long it takes. No one is all evil. Everybody has a good side, just keep waiting, it will come out.

People lie for lots of reasons, often because it seems like a way to get what they want with less effort.
