I really have only had one job my entire life. There are certainly things about it than are fun and seem like "play" instead of work.
Mowing hay-----turbo fun, I could do all day every day and be happy. Thankfully I am the only one who does it at our place and I have/can and will skip fishing for it.
Spraying crops---I like it, but don't love it, it's only fun when I am spraying non-row crops, it's a bit of a chore spraying and fertilizing row crops. My sprayer is getting to be an antique, a newer one would make it a whole lot funner. Just like the mower, I am the only one who does it at our place, it'd be nice if someone else stepped in once in a while, especially when i am busy mowing.
Tillage work or other field work with the tractors------depends, zone building is fun, moldboard plowing is fun, everything else is boring but I don't hate it
Drag lining manure----that's work, and if something goes wrong I curse life LOL. thankfully the last 2 years I have a well trained partner for this now, and that makes it easier, but it's still work,
Shop work-----depends, I like servicing equipment, and really enjoy doing our A/C work.......fabricating, repairs, etc....meh, not so much
Driving truck---------also depends, I like driving 18 wheeler hauling manure, especially when we spread it on the fields with the trucks, transfering to the spreader is not bothersome, but it gets boring, and I loath running 10 wheelers next to the harvesters, especially corn.
Being one of the "old fat guys" now has it's perks. I don't have to go pick up stones out of the fields, or clear hedgerows, or dig tile ditches anymore.
When we had cows, I enjoyed milking, and feeding.....calf and heifer work not so much
