When I had the opportunity to choose, I felt I could find useful ways of doing things. The problem was that I often had to accommodate myself to someone else's choices that had been made years before, and I had to understand what the heck they had done before I could make useful upgrades. And with many ways of doing things, some of which are hugely reliant on really non-obvious behavior controlled by cryptic settings in control files or annotations, that can be hard.
