You would still have to explain to someone what it is that should be documented. A better approach is to learn just enough to do it yourself, but it's not easy

You would still have to explain to someone what it is that should be documented. A better approach is to learn just enough to do it yourself, but it's not easy to document things well. I like to think about documentation like this: Without it your work will be almost wasted as nobody can make use of it. That helps a bit :)
