(just adding as a comment because the original text was too long)

Maybe I reached my goals too quick and without much hassle at all and therefore can't really value what I have.

Changing my life circumstances again would probably not solve it. I always loved and needed to do new things. If I would quit now, I feel like I would lose all credibility. I mean, who wants to hire someone who even leaves his own company only because he is not happy? If there would be at least a reason... But there isn't. Even financials are working fine.

Sorry. Just spitting out what is in my head, unsorted and unstructured. I'm not even sure what I'm asking for with this post.

What's wrong with me?
