I don't take enough "me" time and make effective use of it. I'm easily distracted; I've never been all that great at focusing like a laser on something, and the truth is that I envy the hell out of those who can. And sadly, it's my own damn fault for squandering the "me" time that I do take.
All in all, it makes the writing difficult. What I need to do is keep pushing...otherwise I'll never improve, either as a writer or as a person.
