Travelled: found it mostly extremely lonely to travel alone. Got sick of seeing the same things (this place's contemporary art museum, that place's famous church). Of course I saw some amazing things but I now think I agree with some happiness researcher who claims travel is best in short < 1 week bursts every few months.
Worked on personal projects. I do get some feeling of accomplishment but mostly I just feel lonely and isolated. At good jobs I had the camaraderie of close co-workers who became close friends and we really collaborated. I tried hanging out at cafes and coffee shops and that's better than staying home but not all that less isolating. The random people that show up are not people I talk to or become close to.
I don't feel "free" at all. I'm sure it's partly in my mind. I might also be age differences. I'm older and need to think about retirement I realize I can't just make any random decision because there isn't time to correct. I tell myself I don't feel free because I don't have enough money to never work again. I do have to do something that earns significant income (enough to retire in 10-12 years). If I did have enough to retire maybe I'd still not feel free like not having enough to do X where X is whatever (fund that project, whatever...) though maybe I'd feel free to do things and never worry about income (volunteer for various things?). Now I don't volunteer because that's not going to help me earn money to retire. I'm not sure I'd volunteer or not.
I'm pretty much completely lost at this point. No idea what I want to do anymore. I waste my days reading HN and browsing the net and working on personal projects that have no future prospects and answering questions on SO. I go to a meet up or 2 a week and that's about it.
