Replying to At a crossroads, advice needed

Seeking advice from NS because I relate to the skiing community, and you guys provide great perspective. I will be graduating with a degree in Diesel Technology. The pay is great in this field, however the the stress load on the body and mind are stacked against me. Most people in this career barely make it to 50 years old before they are riddled with back and joint issues.The nature of this work comes with the occasional mandatory overtime (dependent on client needs) as well as drug screening. I will have to find another source of income eventually given the tolls on the body. I was giving thought to a lifestyle switch up today. I was most happy when cannabis and skiing were playing major parts in my day to day life. So why not become educated and qualified in the position of master grower cultivator in the rapidly emerging market of recreational and medicinal cannabis? This change in quality of life would allow me to pursue my passion of herbal medicine while being able to enjoy skiing. Would this be a mistake to pursue unconventional work?
