Friedrich Nietzche (1844-1900) was an Existentialist philosopher--a seeker of the meaning of life. His writings are considered profound by some and absurd by others. A lot of folks think he was just plain nutty. One of the principle themes of his work is the will to power, which he believed was the main driving force in humans. Heady stuff. Dive down that rabbit hole if you like, but if you're here for your career, maybe let's just focus on finding meaning in your work. If you're looking to transition from your current job into a career in the performing arts, it may be time for a reality check on what that means.
Throughout my career I've seen hundreds of resumes, cover letters, and applications, and I'm still surprised at the random approach some people take when looking for a job in the performing arts. As an employer it's frustrating because you know the applicant didn't bother to read the application. Never mind if they are qualified for the job or not. I suspect for them there's some romantic notion of what it means to work in the arts, and so they toss in a resume and hope for the best. When you loathe the job you have, or need a job to survive, I know it's difficult to put effort into searching for work that is meaningful. But casting your resume into the wind isn't going to do it.
Nietsche was not a big fan of work, actually. From a preface to an unpublished work (The Greek State) we have this nugget:
We moderns have an advantage over the Greeks in two ideas, which are given as it were as a compensation to a world behaving thoroughly slavishly and yet at the same time anxiously eschewing the word "slave": we talk of the "dignity of man" and of the "dignity of labour." Everybody worries in order miserably to perpetuate a miserable existence; this awful need compels man to consuming labour; he (or, more exactly, the human intellect) seduced by the "Will" now occasionally marvels at labour as something dignified.
Yikes.
Working in the performing arts has its rewards, but it's still a job. If you're thinking about transitioning into this field from another line of work, it's definitely possible, but it takes work to find a way in. Put some effort into understanding the job you are applying for. Your skills are transferrable, you just need to find that niche that can make you stand out.
Artistic Creativity, for the Greek, falls into the same category of undignified work as any philistine craft. However, when the compelling force of artistic inspiration unfolds in him, he has to create and bow to the necessity of work.
At least Nietzche had a soft spot for artists.
