I’ve wasted a lot of time trying to convince people of things.
Guess what works better?
Letting people know your own preferences, telling them yes or no according to your principles, and when you can’t do this peacefully with people, time to move on.
The truth is, most people don’t want discussion, they just want to be right but don’t make it your business.
People rarely change their opinions, most don’t know how, be with people you can be yourself with.
