We all have them.
Everyone has things that they are interested in. Most people will start down a path, figure out where it goes and what’s involved, and then decide if they want to keep going or not. I’m no different than that regard than anyone else.
I think a lot of people are reserved about their interests and think that they are not something to share. Maybe they are concerned about what others may think (politics comes to mind). Maybe they are solo activities (hiking, reading, etc.) and maybe they don’t think others share them (“Does anyone else like _____?” is something I see a bit of). A lack of confidence in the form of, “I couldn’t possibly do that.” is out there as well.
I don’t subscribe to that way of thinking for most topics (though I have suffered from the lack of confidence all too often).
I enjoy learning more things, and sharing what I know. I enjoy the discussion and elaboration of ideas so that we, as a community (locally or worldwide) can move forward in ways that an individual cannot. The Internet has made the doors open for this sort of thing, and I think that’s awesome.
Given that you are here, it’s very likely that you and I shared in a conversation about something one or both of us has done. This is the likeliest place to find that information.
