from wikipedia: "Evolution is any change across successive generations in the inherited characteristics of biological populations."
from me: "Evolution(clearly biological) cares (a cute way of saying is effected by) about nothing but survival." The personification of evolution was perhaps a bit too cute, but I feel it's also a bit more inspiring than getting specific. Also, I can't see much of a difference between surviving and being naturally selected.
Please let me know what I'm missing.

I think it's OK to abbreviate like that when talking about evolution, as long as we're aware we're anthropomorphizing. Note that the definition from Wikipedia that you quoted says nothing about "survival". Death isn't even a requirement. You just need a change in the allele frequencies of a population to call it evolution. With that survival line you were probably referring to natural selection, which is just one of the aspects of evolution, and again not a requirement for it. You can have evolution by genetic drift, for example. But even if you were just talking about natural selection, putting the emphasis on survival (and "nothing but survival") is incomplete and misleading. Death/survival don't need to play an important role in natural selection (though there are instances when it will, of course). For example, small differences in the average number of offspring already mean natural selection.
