I often try to get involved in communities around my interests, but I'm not very good at staying in touch. I've been involved in many over my time - he says as if he is a 90 year old man.
I tend to go through a lot of phases. Sometimes I'm really involved, other times I dip in and out and sometimes I'm nowhere to be seen. Oftentimes, that ties directly into my real life. If I'm busy at home, I'm not productive. I'm looking to pick up a development laptop so I can make stuff while hanging out on the sofa with my partner. I've not managed the balance yet - I do too much of one or the other.
I've met many interesting people like this, mostly via online communities. This mostly includes gaming communities; Phantasy Star Online, World of Warcraft and Rocket League. Most recently, Makerlog and 200 Words A Day. These are two communities I aspire to be more involved in, as they encourage actions I want to enhance - writing and making. I don't feel like I'm great at either at the moment.
I amazingly still keep in touch with a handful of people that I met on World of Warcraft, but I suppose that's to be expected from a decade of playing. If I can keep in touch with a handful of people from a more productive community, maybe we can do great things together. It's difficult to go alone.
