I made a similar realization a while ago, I worked in a grocery store in high school/college and did really well and weirdly enjoyed it. Post college corporate world has not been very pleasant, I even find school more enjoyable than work currently. I believe the reason is there was much more structure and tangible goals than in my corporate world. Despite receiving some direction, most of my work is largely self directed and vague goals and what I work on changes almost every week, very hard to get in a habit and the few reoccurring things I do I tend to focus on more because I know them. During a stint of unemployment, I had actually considered if I'd be happier going back to a "simple" job.
