When there is little space between what you do and who you are, we go a bit nuts when we feel under threat. We flip out, throw tantrums, retreat, stop trying, or become apathetic. The way to fight back isn’t to double down or further insulate. It’s to diversify. A diverse array of experiences creates a resilient self, and research shows it leads to a happier, healthier you. Diversify yourself. That’s the true key to being someone.
