Is this what burnout feels like

It is 12:30 AM as I write this. I am trying to connect to the laptop that I hastily set out for the new person starting tomorrow. The new person who we got last minute notice for and for whom I rushed to find a computer. It takes an extra amount of time because the remote control software has the old name for her computer from the last person to use it, and the name on the computer itself, the name I changed today is misspelled. Some minutes of searching and renaming and rebooting later, that part is straightened out.
I am struggling to care.
I need to configure her browser settings and set up her email. I need to do this at midnight because I didn't have time to do it during the workday and couldn't stay late due to familial obligations. I am doing it at midnight because if the computer isn't ready before the user comes in, I am going to have to explain myself to HR. Nevermind that we don't have enough inventory to have these things set up in advance.
It was a long day and now it is turning to a long night because the password doesn't work. Several tries later and I'm in. I plug away and set check boxes and server names. I have done this so many times that I can practically do it in my sleep, I only care because I have been twice hassled by HR and various other departments for not having the computer ready. These delays have caused no actual delay in use of the computer, but the hiring manager gets pissy and then I have to spend an hour emailing back and forth about what went wrong.
I think this is what burnout feels like. I am working to keep from being hassled but not to do good work. I am getting tired of solving the same problems over and over again.
Maybe its just late and I need to go to bed.

Why I don't jump in

It seems that  I have been struggling with being an artist for most of my adult life. I have struggled with the definition, variously using the terms craftsman, artist, and maker. I have also always stood on the edge and never jumped in with both feet. I have often asked myself why I don't throw caution to the wind and try out the life of an artist. What would it take for me to take a year off and be an artist?
I never have because of two main factors. The first is my own unreliability. I can gain a proficiency in most things in short order. I inherited from my parents; an ability to soak up different techniques like a sponge (an ability that my mother only discovered in the last few years). I can sometimes pick up a new craft by picking up a book and reading about the process. This is how I learned meadmaking and bookbinding. The trouble is that I can never seem to stick to it. I find reasons to stop progressing in one domain and move on to another. It can be because the next step requires costly tools or materials or that I am fascinated by something else or it can be that the other projects or life goals get in the way and I give up.
The second deterrent factor is the examples I have from the two truest craftsmen that I have personally known. My father, who is cursed with the same wandering attention as I have, spent a number of years doing custom cabinetry. It was an unsustainable model based on a high level of skill with quality materials against the wearing down of the crafstman hour by hour. He eventually had to leave that line of work. The other example is of my high school ceramics teacher who kindled in me my love of pottery. He told me of his early days as a production potter where he would work constantly to produce salable pottery and then truck it around to galleries trying to get his work shown. He eventually moved to the world of teaching where he could have a more reasonable schedule.
I don't think that I can live either of these lives. I cannot throw away my steady reliable job to give this a shot.
Can I?
