Then one shouldn't go into a recreational field as a main source of income. I know because I made my living skiing for 4 years. That said, I wouldn't change any of it. To date, it was the best 4 years of my life. I lived off potatoes, ramen noodles, and beer. It was clear, early on, that if I wanted more than a truck that may or may not start, I needed to make a change. One can look around at those who've been there for years and years to see that.
Also, it doesn't take much research to see what kind of pay one will be getting into.
