Well, to be honest, you have to like working too hard for little or no pay, and starting your day too early, but you do get your winters off, unless you get into ranching also. To be honest, it is not how it used to be when I was growing up, due to corporate farmers like ADM and the like, but if you want satisfaction at the end of the day, then do it. And I wish you the best of luck!
To be a good farmer, you need to be outstanding in your field.
Nothing, you don't need any qualification or any courses.
You need to talk funny nd be smelly but unfortunatly those university courses weer cancelled in the 1950s
