This seems to generally be a hurdle of remote work. It's hard to feel that sense of camaraderie when you are far away. There's a lot of reasons for this that aren't about you or them: like lack of face time, voice communication, out of sight out of mind, hard to get to know a remote person personally without "watercooler" talk, etc. It's also pretty common that remote people are left out of promotions and exciting projects for these reasons.

I'm a bit nervous on the 7 jobs in 10 years. One phrase that comes to mind is "10 years of experience vs 1 year of experience 10 times." Maintaining/operating something you've built is a key step in improving your skills, since you can see your own mistakes and learn from them.
