life advice?

[aroraborealis]

As I've commented, I love reading graduation speeches, because it's so interesting to hear what advice people give to people just starting out on adulthood. Even though I've been an adult (by some definition of it) for about a decade now, I still learn a lot from this sort of thing.

What nugget of advice would you give to people on their way through life? Would it be different for recent graduates or others? How?
