I found the same thing with farming. During my first few University years, I financed myself working on a dairy. A couple of four day weekends each month I would drive around 150km to the job and also the same work for three months solid over the summer holidays.

While I wasn't crazy about the 05:00 starts and shifting hundreds irrigation pipes twice a day isn't a whole lot of fun (but great fitness training), I did find tractor work to have a zen of its own. Around and round and round a paddock ploughing, sewing or mowing was pretty therapeutic and allowed my mind to think on all sorts of things.

At one point I seriously considered following a more agricultural focused career. Ultimately I didn't go this route, but still often wonder about my life if I had of made that choice.
