John, IMO learning a piece of software does not make an editor. Yes, you need to be proficient with your tools but read and study what makes an interesting program/show.
I went to film school and learned a lot of valuable theory and aesthetics; but zero skills to work as a professional. I learned those by interning and getting work in anything related to the industry, finding good people who are willing to share their knowledge and experiences (there are more than you think) and asking them lots of questions.
Its a tough way to make a living, its a fickle and unpredictable life.
I would suggest trying to get an internship or volunteer to work for free at any type of produciton company to see how you like it and go from there.
