The best work experience I ever had was working in a warehouse where I just unpacked and repacked lumber all day. It was a lot of nonstop lifting. I felt happy when I went home because I felt like I worked hard and got stuff done and it was really good exercise too. I did that work because I didn't know what I REALLY wanted to do after quitting my job (disillusionment and naive startup dreams without knowing what it took to succeed) and I wanted to experience hard work that wasn't in an office (i.e. work in the trenches).

Someone I knew told me I could work in his warehouse. It's too bad that it was so low pay. If the pay wasn't the issue, I wonder if staying at that kind of job would actually be really good for me. I would be physically healthy, my mind would be clear and refreshed all the time, and I would feel good about having worked hard every day. Would the positive effect still last if I did that work for years, or was the positive effect only temporary because it was a novel experience to me at the time (and I didn't care about the low pay at the time)? Interesting to consider.
