In my 15 years of experience the true happiness comes from the ability to choose what you want to do and avoid things you don't. So if you in the place there you can specialize early in your carrier and know what you want to do - go for it. But in my case I never had this chance in my first ~5-10 years in the IT. I lived in 3rd world country with like 3 IT company in the town. So I had to be generalist. Right now while I'm still capable of doing more or less everything, I have my 'standards' of jobs I'm willing to do. For example I don't do frontend, not because I can't, but because I prefer to not do it. So basically right now I have a set of things I enjoy and I try to make sure I work on them. Probably I would be in a much better position if I could specialize in more complex fields (in terms of career opportunities), but at least I have enough experience to have some options I like.
