Im sort of in a similar situation too - all of my living situations are only temporary, they last a few months - I don't have any financial or other commitments; and I feel like most old friends have moved on, or are living their own lives - money is not really an issue in the short term, I could totally travel for a few months.. but I kinda feel like I already did that when I was younger!
I have plenty to do; working on my projects like this forum keeps me really busy and getting up every day is exciting because I know there's something cool I wanna do.. BUT at the same time; I find myself wondering what Im working towards.
Its great doing all these lil projects; but its also mostly just me working on my own, and I feel like I should be doing something bigger; I know I love making games and interactive projects, I don't really wanna do anything else! I have been interviewing for a cool job; that would definitely occupy me for a few years - but even then; I think I wanna start some big project; like a real games or digital art studio; I want something ambitious that brings real meaning and risk into my life.
It sounds like it might be a bit similer for you? I suppose a lot of people here are in the late 20s - early 30s; I think this is just what this age feels like
