I can't talk about a civilian mindset or normal corporate culture, but hacker culture could be both the easiest and the hardest to get in to.
All you need is yourself and a computer (or some other device to hack, but computers are ubiquitous), then do some hacking and optionally reach out to other hackers for advice or to show off your new hack.
The hard part is having an interest in hacking and the absence of a canonical roadmap of "how to become a hacker".
What is it you seek? A sense of belonging? A more "normal" life? A predictable career path?
80% of my 6+ years of being a software developer has been working on software projects alone with no team. I have been a remote worker the last two years which only compounds the problem of being isolated. I love my job as a developer but I am definitely overwhelmed with a case of imposter syndrome right now.
I am dissuaded by some recent job rejections for positions I felt reasonably qualified for. I can accept a no but to be ghosted after several rounds of interviews for a position is just demotivating.
On the bright side, if it is a personality problem on my end then at least I have the power to fix it.
