It’s usually considered a faux pas to “reply all” to a group email if the reply isn’t relevant to the entire group. But if everyone in a group email represents a life challenge, you do want to select “reply all”.
According to this quote, by Mike Gafka, that is key to success. It’s about responding to all the challenges that come your way, not just the ones you like or the ones that are easy.
The more you do this, the more the enormity of a challenge begins to matter less. Whether it’s a big or small challenge, you’re going to accept them all the same. And suddenly, the fear and anxiety that comes with the more major challenges will begin to subside.
