Let’s say I have a command called “enjoy.” I’m expecting enjoy to give valid output and an error message. How do I call enjoy such that the valid output goes to one file and the error messages go to another file?

Assuming of course that you’ve used STDOUT and STDERR properly and you’re using a nice shell. If you’re using csh, you need to do something more complicated:
This works because
>&redirects both STDOUT and STDERR – but STDOUT has already been redirected. The parentheses make sure that STDOUT is long gone before the data gets anywhere near the overzealous>&.
