Well, your job is just that - a job. We all need one, we all would rather be doing something else but why not make it work for you? Use it to find fodder for writing a book. Nobody says you have to be tied to cutting hair - I have my license and do something totally different for a living. In any case, just know that you are NOT tied to it. Life is too short to do something you dislike day in and day out. Look at cutting hair as being a back up profession. Keep your license up to date, do a little kitchen cosmetology on the side for your friends but know that it's not something that defines you.
