It’s perversely fun to tell yourself this, and especially fun to tell your teammates. You get attention, you get to be talked about, and you start finding confirmation everywhere that you’re right: “Everyone feels the same way I do.”
No they don’t.
It’s easy to talk about leaving. It’s difficult to stay. I don’t know anyone who’s led a rewarding life by continually quitting when things get difficult.
Moreover, people who quit for the right reasons probably don’t need to tell anyone about it.
