My dairy farmer son (previously sheep farming) would disagree, as would many farmers.
Farming today requires:
Physical fitness and good health - if you have a bad back, a dodgy knee or asthma for instance, you might struggle with a job in farming.
Good maths skills - some of us are mathematically minded. Some are not (regardless of how much education one has)
A desire to work with animals and an understanding and commitment to animal welfare. If you don’t like animals you are far more likely to mistreat them (intentionally or not)
Common sense and the ability to find solutions to things.
Commitment and dedication-if you genuinely don’t enjoy the country life, farming isn’t for you.
It is no different from many other jobs. We have talked a lot about rest home caregiving in various threads lately. Not everyone is suited to that kind of work. I know lovely people who tried it because they wanted a job that was meaningful and rewarding. Smart, intelligent, caring, wonderful people - but they found they simply couldn’t deal with the personal cares side of the job. That doesn’t make them lazy or unwilling to make sacrifices. It makes them honest enough to admit they are not a good fit for the job. It is very easy to go down the “any job is better than no job” road, when you are not walking in job seekers’ shoes.
I’m pretty sure there are jobs out there you would not want to do, or would not be suited to. If someone forced you to do them anyway, you might see things a bit differently.
