I'm going to pick up camping/hiking as a hobby. I operate day to day with a base level of stress that I think is way too high. I've worked hard my whole life to have a stable home and life for myself and my wife, and while I think we're doing a good job of that, I still have a lot of anxiety when I think about how fragile everything is. I have a never ending to do list, and when I'm not doing something on that list (like working on a hobby, or just sitting around) I feel guilty.
Mind you I'm not complaining, I understand that my situation is better than many. But my brain is firing away 24/7 and never gets a break even when I'm trying to relax.
