I came across a website today (thanks to the folks at r/survival). At first I just added it to my favorites list thinking that I would add it to the main CNI page as a Daily Insight link. But the further I got into the site, the more I thought, this is something that needs it's own blog post.
So go to this website, and read the whole thing. Every page. Then go to the workbook and do every page in the workbook. That's your survival lesson for the day.
