That's not so easy, but also not as hard as you think. Won't take a lot of time on any one thing to see if it clicks for you. Pick a couple of activities, do each from absolute beginner level, twice a week for four weeks. Once if you're pushed for time. Keep the one that sucks less after a month. You don't need to hear the voice of God to download the Couch to 5K running app, grab a basic weights set and watch a few vids on simple exercises, or sign up for a local yoga or spin session.

The high can be way better than you'd believe possible before you try. Or if you don't believe personal anecdote.. /something/ must be keeping all those people coming back to it at considerable expense, hassle and time.
