Opportunities really do come out of nowhere. It's risky to leave any unexplored. But use a priority queue. In other words, feel free to turn people down while you're busy, but don't forget who you've said "no" to. Over time, a person's priority goes up, just like when you're fixing bugs. If you've said "no" 3 times to a lunch, eventually you should say "yes" even if you are still busy.
