Definitely agreed. The greatest flow state I ever had was building a "raft" out of small logs and lots of cord on a rest day on a backpacking trip. It took hours to gather wood of the right size, break apart the pieces that were too big, scrounge around for all the cord I could find in my gear, arrange the wood in a sensible way, and tie it all together. During all that time I was so focused on the task that I don't think an unrelated thought even entered my head. It was completely useless: I had nothing to use the raft for, except to swim out a little farther into the lake than I could by myself. The raft didn't even work very well! And yet building it was tremendously satisfying. I can only imagine the satisfaction one might get from a task of similar complexity, but that's essential to one's survival!
