I have to accept the fact that my judgment is fallible sometimes. It's really hard to do because I think so much and try to make the right decisions up front so I don't have to pay a big emotional bill later. But as whatsisname always says, we have to make most decisions based on incomplete information. We see a tip of something sticking up and have to figure out whether that's a hazardous iceberg or a nice safe buoy, because we can't tell for sure.
The other thing is that people sometimes surprise you. Sometimes they turn out to be a lot cooler or stronger than they appear, although that's relatively rare. More common are people who seem kinda nondescript and turn out to be super neat. So I guess one is going to get a few bad or at least sour apples in the bunch too and I won't sweat it. By the way, just in case anyone needs to hear this, if you're on my f(r)iends list this post is in no way referring to you (except maybe for the part about people turning out to be super neat :D).
