Thank you, everybody, for kind words and good ideas. I'm not going to quit my job any day soon even though I'm mightily frustrated sometimes, if anything I'm more likely to analyze things to death before I do anything...

I think I'm in the process of sieving it out exactly what it is that frustrates me most (whoever wrote "the mills of God grind slowly but they grind exceeding small" was thinking of governmental processes) and seeing how I can change that while keeping the parts I like. I don't think I really want to ditch the analytical, theoretical parts of my job, 'cause I could analyze the elements out of sheetrock, I just want to see more results, get more feedback, and work with something I find more meaningful.

Thanks again!
