Good advice, but the boss could still simply be a sociopath...
I believe most bosses are sociopaths by definition. Who in their right mind would sell their whole existence, while driving other people to the brink of insanity or depression, just to make a buck?
Money helps in life, but there’s more to life than that. If you can decipher the thoughts and actions of the boss, then that’s when veil is lifted and you can see the truth. I refuse to let the boss’ desire for riches tamp down my desire for happiness. I can however show the boss that he needs my help in exchange for making my life better.
