Deciding What Not to Do

I recall an early conversation with my advisor, a couple years after I completed my PhD. I was worried about not having been invited onto any program committees when others in my cohort were getting such opportunities. He assured me that it would come in time, though I was still anxious. He was right; after another year or so, the invitations started coming. At this point, I need to decline most of them, or I'd spend all my time reviewing.
