Feel free to stop reading this if your career is going great, you're thrilled with your life, and you're happy with your relationships. Enjoy the rest of your day, friend, this article is not for you. You're doing a great job, we're all proud of you.
For the rest of you, I want you to try something: Name five impressive things about yourself. Write them down or just shout them out loud to the room. But here's the catch -- you're not allowed to list anything youare (i.e., I'm a nice guy, I'm honest), but instead can only list things that you do (i.e., I just won a national chess tournament, I make the best chili in Massachusetts). If you found that difficult, well, this is for you, and you are going to fucking hate hearing it. My only defense is that this is what I wish somebody had said to me around 1995 or so.
