It's working wonderfully well for me -- all the time I've wasted fruitfully spent on the internet is finally paying off.

I totally recommend doing the exercises in What Color Is Your Parachute. One thing I've discovered, since developing that list of skills and interests, is that things I'm currently doing (part-time work, volunteer work) can be aimed and directed in such a way that it gives me more experience and accomplishments in the things I'm most interested in, so it lets me get the best use out of what I'm already doing. (Like, for instance, I get called in to substitute as office manager for my church every now and then, and with that list in hand, I can look around for projects that fit into my desired direction.)
