I bought my wife a kite for her birthday as something different to try, and we went to a park to fly it today. It was instantly fun; we stayed out there for about an hour enjoying it the whole time. I think it may have been my first time ever flying a kite; I don't remember ever doing it as a kid.
I'd say, as an adult, it's somewhat rare that I actually have fun. I may enjoy something to some extent, but it's not very often that something evokes the feeling I'd describe as "fun". I think this is because it's really easy not to do anything these days, mostly because of screens everywhere. I sit in front of a screen all day at work, and then I come home and watch things on a screen (TV) or get on my computer at home to read, watch videos, or play video games. Most exercise (i.e. time away from screens) is contrived: running, weight lifting, and to some extent cycling (this can sometimes be an activity unto itself though, especially if off-road), for example. Flying the kite, on the other hand, was exercise for free (running around without doing it just for the exercise). There just aren't a lot of "real" things that hold one's attention, probably because they are not passive and do take some level of effort and thinking.
I've also noticed that many of the things I find fun are exhilarating, somewhat scary activities that usually require certain environmental conditions (weather, terrain, timing), like riding a roller coaster, mountain biking, zip-lining, and white water rafting. Since these things feel dangerous and are not things I can do at any old time, I have an aversion to doing them even though I know they cause fun.
I have thought about doing a screen fast (at home since I have to use one at work), but the thought of filling all my free time with real activities sounds difficult. I suppose I could clean or read to fill in the gaps.
I guess the moral of the story is that I don't want to waste my life sitting on my butt in front of a monitor or TV, but I end up doing it most of the time because it's the path of least resistance. Do you guys ever feel like this?
