I most humbly disagree on some of these.
I do agree that if you are running around in uncharted areas, or unpatrolled roads, definitely don't go alone. Good advice :D
Again, I couldn't agree more. Breaking contracts is a good way to get everyone against you. No one can trust the guy that keeps getting loans and defaulting. Eventually it will catch up to you.
This I take issue to. If there is going to be a war, do not just leave. When everyone leaves, the opposing faction can just waltz right in and now you have a fortified enemy watching you retreat. If there is war I say bunker down with communities for the "safe" option. Or go to war and provide that safe option for others.
Again, false. Well I guess not false just an opinion. I feel I have found a community where I can trust some of the people in it with most things. Never met them in real life, but if I go away on a quick adventure I know there are some people I can trust to feed the herding dog, maybe give them my spare key, and that when I come back my coffers won't be empty.
I don't think most duels will go as far as CDG, so I would alter this one to "Make sure you only duel with a crowd" or some such, so the guy doesn't steal your wallet and cut off your head to get to it.
Again don't leave. Fix it. Appeal to whoever is above the judge. The only time I would suggest leaving for corruption reasons is if your King was corrupt... Really no one to go to at that point. Guess you could go complain at the sedecim, lol
Getting rich gives you a target that you get to wear around! Sure you can put your funds behind walls, in a safe, or what have you, but I feel like you can skate by a little easier in life without drawing the attention of every cutpurse, if in fact your purse wasn't as heavy.
Great list nonetheless. Just adding my two cents to spark conversation
