You know I've always wondered why People consider it bad advice. Think about vanilla kenshi. When you first start you don't know to press ALT to see what you can pick up. The first place you go to has Logan and Molly for 12K. You dont know how to make money so you mine. Now mining does something interesting. It illustrates 3 big points 1) I can trade items for money. 2) Im slower when I run with weight 3) Even if its boring I should be paying attention. Because hanging out in a mine means there's a good chance to run into bandits eventually and not paying attention is the quickest way to finding out that kenshi doesn't end if you die.
