I think it was Mark Twain that said, to a man with a hammer, everything is a nail. While that's a funny saying, and all too true in the IT world, it's really not a good way to go. Sometimes the best use of a tool is to not use it.

For example, I've done a lot of work that used dynamic SQL. To properly use dynamic SQL, you almost have to have a well-maintained metadata repository. Well, the first thing I found out about metadata was that there was a limit to how much you could automate it. Too much automation made it brittle and easily broken.
