> Controlling emotions. Reduce negative thinking and fear. This avoids distracting thoughts during a critical mission. This is my favorite one because I just find it so funny. I once saw a video series of a survival guy on YouTube and they brought him to an uninhabited island for 7 days. And in the video log he kept on insisting about how „beautiful“ everything is and how he loved being there, meanwhile becoming severely dehydrated and having been without food for days on end.

well, the solutions can be implemented and IMHO are based and rooted in the Stoic way of thinking. Overall, its a good manual that you can just train your brain to learn IMHO. (or you can just say the Dune "Fear" mantra all over again :D) Survival questes are always a laugh though :D
