People are so pointlessly concerned about burning bridges, even when they themselves get mistreated.
I will burn the bridge and the damn entire town too when someone treats me poorly or gets on my bad side. I do not give a fuck. This policy has served me very well in life, by the way, even before I had a boatload of money.
Accepting abuse meekly just invites more abuse, whether you’re talking in your personal or professional life. And I refuse. I endured that for too many years.
