Technically this was said by Schwarzenegger's character in Predator in response to an unseen monster that was killing everyone, but had been apparently injured: it bled, ergo, it can be killed.
I decided this is actually a great metaphor for all of life's problems.
Which is to say, given a problem, no matter how insurmountable it may seem, all I need is the tiniest bit of progress on it to make me think that I can eventually get through the whole thing. If it bleeds, I can kill it.
