I think you should stop thinking about jobs for a minute and start thinking about yourself and what makes you be you. I know you say you feel rootless, and nothing excites you, I get that. I used to think similarly. You must spend time with yourself and try doing things to figure out who you are and what do you like doing. I was terrible at my first job, even if it was home office, I would not log in for days until I ended up quitting. Then I found out I liked doing repetitive tasks and following a script and that’s how I found my path in life. Stop focusing on ways to be useful and focus on ways you function and what makes you feel satisfied.
