Keep friends who are proud of you without feeling threatened by you.

Good news is a test that most friendships pass quietly and a few fail. Watch the first few seconds after you tell somebody that something went well. The ones who are genuinely glad make room for it; the ones who feel smaller will change the subject, find the flaw, or match it with news of their own. Neither reaction makes anyone a villain, but it does tell you who to bring things to.

Next time something goes right, notice who you instinctively want to tell. That instinct is usually accurate. Put a little more into those people this month and expect less of everyone else.
