I'm seriously trying, but I haven't seen it be all that helpful for complicated stuff. I had a bug where we were running out of database connections and cursor wanted me to create a wrapper class for the connection pool that would count connections and block if there were too many. Obviously that was dumb and I didn't do it. Turns out I needed to actually understand the problem and then I was able to fix it without too much trouble. On the other hand, I made a whole website in 2 hours without touching any of the code directly, but it was really simple and had no performance or security concerns to worry about.
