You Should Write a Book
You may not feel like you could write a book, but you actually have a lot to say. Just let it flow!
You already live in your own little world. You may as well introduce everyone else to it.
It's likely that you feel like you have a lot of baggage you'd like to unload, and writing can be cathartic.
By writing a book, you would feel a huge sense of accomplishment. And you'd have a legacy to leave behind.
