You sound an awful lot like me. The first 3.5 years was great, maybe even stretch that to the first 5 years. All downhill from there.

I'm starting to understand why everyone says the best jobs are never on public display and you should network and making a brand for yourself. Working actively on that now, will see where that brings me. Also working on my own projects. The most important point for me is to try to make it better.
