However, just because there is always something to do doesn't necessarily mean it is smart to be doing it. Are the farmers who are always working on something better off for it? I unfortunately do not have sufficient data, but I wonder if working less could actually lead to increased profitability? Based on my anecdotal experience of observing neighbours, I think there could very well be some truth to it.
It sounds like you've got a hobby farm. I could be way off kilter, but if that's the case, perhaps you're not as financially dependent on every crop, and can afford increasing the risk of disaster? I freely admit to not having any direct on-farm experience for 20+ years, so it's fair to say I'm a bit distanced from the devil in the details now.
What you say is the worst excuse I have heard in a long time, and betrays a fundamental lack of understanding of human psychology.
