I agree that I tend to enjoy my personal projects far more than anything at my company. My typical problem is that I burn out quickly once I get really into anything long term. And frustratingly, I tend to want to work my own projects most when my work gets most stressful.
I guess it's just hard not to get attached to something you spend so many hours working (and unintentionally thinking) of. But this sounds wise advice.
Yes, considering it as a paid education always helps. I don't really think of anyone here as a mentor, so I usually have to study on my own to learn what I need, and I still tend to regret most design decisions I make. And there's just that looming feeling that everything I've worked on is ultimately worthless. But I guess all of this is just part of the software development job, ha.
Interesting that you say jumping damages the personal image, since it seems what most others here advocate. This job gives me good perspective, so I still wouldn't want to go elsewhere without convincing myself that it's a meaningful improvement.
