This would have sounded like absolute woo-ey bullshit to me a few years ago. Until I worked at a place that turned openly hostile toward me. On a work trip, I realized quite literally:

“If I’m smiling, those people who care about me will be happy I’m happy. And those people who hate me will be PISSED I’m happy.”

It’s perfect. It really is the ultimate “fuck you” rebellion, as silly as it may sound.
