In my former career, I often said “I tell selective truths for a living.”
How cute and clever.
In reality, I worked in public relations. You could say I talked for a living.
People said I had a silver tongue and could persuade any skeptic. My view is that I’d become so convincing by learning to believe whatever BS narrative I was shoveling.
You don’t need to work in PR to get good at bullshitting yourself, however.
