2 separate ones, in fact.
I always wanted to write books, so a few weeks ago I started typing on microsoft about, and brainstorming ideas I had. I started writing one serious policy book, and one dystopian novel. I dont want to talk about the subjects specifically, but I have like 190 pages completed between them so far.
I find the writing therapeutic, and expect nothing to come from it commercially. But that's not the point, It's just fun. I'm passionate about it, And when I smoke a joint and drink whiskey and at 2am and hack away, I feel like a badass Hunter S. Thompson type.
Its a good hobby. Very solid hobby.
