I'm with Steve: Environment and co-workers are the real deciding factors. You only "land" or "end up" six feet under. Even then don't be too sure. 😀
I can't be micromanaged. I put up with A LOT of it doing field support for several years, but to some extent that's the nature of the job. So now I'm in a position where it's me and the boss, and he's been shanghaied into a lot of financial and analytics work - mostly because I showed up.
I'm really the geek, the office nerd, the computer guy, the local help desk, the database guy, the Accidentally-on-Purpose DBA, ad nauseum. I work a 40-hour week (with rare-to-occasional off-hours support as is always the case with IT). I'm not my own boss but I'm probably the next closest thing. I've got a lot of latitude in how I do my job. I've got my own SQL Server sandbox to play with. I can pursue pretty much any project that interests me. Sometimes they actually prove useful. Most times I'm just learning some principle of relational databases or some technical point about SQL Server. I've always got to be exploring, learning and chasing stupid little rabbits that cross my path now and again. I've got to set things on the back burner to boil and bubble until something useful pops out.
In short, I get to play with cool toys at work and they actually pay me for it.
Not to say we don't have our challenges (John Sansom had a SFTW link to an Inc. story on "The Law of Crappy People" which is a great read and a fair description of certain parts of our company, but I digress...). But the team I work with in my office is overwhelmingly comprised of people who care about the work they do and do it well. That's rare in the workplace.
My wife and I joked for several years we felt like the Isrealites following "a pillar of fire at night and a pillar of smoke in the daytime." We'd park somewhere for a while and when it became obvious it was time to go a different direction we'd pack up and go, sometimes literally. I came very, very close to leaving my current job about this time last year (along with almost everyone in my office) due to reasons which are much too involved to explain. But things settled down and I'm having a grand time of it. When the pillar moves, I'll be on my way.
Just my $0.02 from over here in the cheap seats of the peanut gallery - please adjust for inflation and/or your local currency.
