I'm sure many people can name what sucks about their job, I mean, it's a job afterall. You get paid for it because no-one in their right mind would do it for free. What would one expect?
However
What do you LIKE about your job? Even if it's just that tiny little thing that makes it worthwhile more often or not?
My "real" work is in music. I made lots of money in photography (401K and all that, too) and I enjoyed that also, but I don't do it for free, except for friends. Making music with my friends (acquaintances, really - obsessed musicians are as hard to know as auties) is more enjoyable than anything else I have known and anytime I have the opportunity, I go do "my work", with or without pay. The technical end of live music performance is THE one pursuit where I am totally confident and undaunted by any challenges. I own it!
Recently, I had the chance to work with a group of jazz musicians from a university at a big Jazz Festival, locally. As things worked out with my adult son who I had not yet met, the meet-up fell on the weekend of the fest. I had to cancel and fortunately I did it early enough to keep that bridge from catching fire. It ripped me up to abandon a chance to make music, even though I am "just the techie", and not a stage musician. I care nothing for the stage. I want to be behind the scenes, anyway, but I can make or break any band with my in-depth knowledge of acoustics, equipment, etc. as those are my lifelong studies, paid or not - doesn't matter.
I wish for everyone to find a lifelong interest.
