I hope surviving shipwrecks and such counts as getting hard things done. "Safety and Survival at the Sea" has a lot of those. Chapters like Fire, Man in Water, Man on life raft, Man in a boat, and so on. Each chapter has many short episodes, just the hard facts, leaving the details to your imagination. I can quote one from memory: "North Atlantic, November. 12 people on a life raft. The raft kept capsizing, righted by walking on the inside of the canopy. 7 survived."
