In high school and college I worked at a Christmas tree farm, and eventually was also a landscaper/hardscaper, caring for, digging up and planting trees, and building retaining walls and patios. At the time it made for good motivation to keep doing well in school, as the hours were long, and while easy for a fit 18-22 year old, definitely back breaking kind of stuff.

However, looking back on it I miss those weeks and months on end of having 6+ hours a day to be outside, working my body, but doing tasks that let my mind wander all over. No doubt those years of daydreaming helped me become the person I am today, and everybody has to grow up at some point, but I do wish I could get more of that back into my daily life. In fact, I think a large part of my current path towards early retirement is just to have that sort of time back.
