The FOMO dilemma is real, for sure!
For me, the worst is when I'm running. I want to be "in the zone," just enjoy the run, the music, the endorphins that start flowing. And I want to keep my heart rate up for the whole workout. And then I see stuff I just have to take pictures of: wild turkeys, the ocean, trees - just about anything is worthy of a picture if it's framed in the right way.
I guess we're just cursed to live in beautiful places. Nice problem to have, though - isn't it?
