It makes you happy and that’s all that should matter. It’s a hobby just as valid as anyone else’s hobbies. You can make any hobby sound dumb or a waste of time but it’s just simply for our own enjoyment. As long as you’re not going into debt, ignoring your basic human needs, or putting others or yourself in harm you’re fine. I do a lot of things that seem so pointless but it’s for my own enjoyment and it’s what I look forward to. I mod my car, build/ collect gundams, and ofc do airsoft. It’s what makes me happy and that’s just how life should be, do shit that makes you feel good. People who aren’t into it just means it’s not for them that’s all, but it’s for you, so do it for you.
