On inclusion In a new group of people, your natural tendency is to introduce yourself to everyone and make friends quick so that you're not in an awkward position for too long. To you, it's common sense and it's hard to make you uncomfortable around strangers. Good for you, but your guests may not always feel the same way. If you bring someone along with you to a gathering, you have a responsibility to use your skill to connect with people to help them connect with people. You have to pick up the slack, because you know you can. It's about making those around you more comfortable. Help them feel included. You don't do a great job of it all the time, perhaps because you're too distracted with your own interactions to worry about others, or you believe that everyone else should figure it out on your own just like you do. However, that's a bad argument for not helping because we both know you need help in certain situations and if you didn't have this help, you might never figure it out. Be the leader and help when you see someone feeling distant from the interaction of the group or uncomfortable in any way.
On missing out The only thing you're missing out on is what you did not and will not do in your own life—not what everyone else is doing in theirs.
On genre What is it that you write? Do you have a term for this genre of writing? Are the Moral Letters a self-help book? Is the 33 Strategies of War a business book? Is The Win Without Pitching Manifesto philosophy? Arguments could be made in any direction for these books because they mean so much more than what their titles let on. As a reader, it doesn't matter because it's your job to synthesize the knowledge into something applicable to your life no matter what. However, what about as a writer? How do you sell these works when you're not sure what they are or how to categorize them? Better yet, if you don't know what they are, how much form can you give them to comply with a certain genres "standards"? As you read True Stories, Well Told by Lee Gutkind, you realized that an entire genre was birthed in the last 20–30 years. Literature has been alive and well for a long time before that. The fact is that your writing should be valuable in some way, and this is the principle of every great piece of prose or poetry ever created. Perhaps it's entertaining, or it's practical, or it's profound and inspiring—maybe it teaches you to live a better life, or it teaches you nothing at all and is enjoyable to consume. Whatever it is, it doesn't matter the genre. You can mix and match whatever the hell you want—I give you permission—to create something worth reading. Value is your only consideration.
