It pays to be suspicious of those who tell you you can’t make an honest living.

Huh, I've always been suspicious of folks claiming the opposite.

For the downvoters, have you ever tried to explicitly map your externalities?

What does mapping your externalities have to do with honesty? Is this a poor attempt to suggest that no one can actually be honest because no one has a full understanding of the entire universe? Because that's just a lazy excuse for not trying to be honest and not really worth being in the debate.

Having externalities does not mean you are dishonest. Hell, you can even ignore your externalities and still be honest. You can even outright steal from people and still be honest.

Yeah on the contrary, it’s been my experience that finding other truth tellers tends to lead to a supportive community, where everyone is relieved they don’t have to put up with bullshitters.
