For reasons unknown to me until now, I've avoided writing publicly.
Well, that's not entirely true. I've avoided writing, in large part, because I feel a burden of obligation to keep writing once I've started. Like the person in your life who feels obligated to stay talking once they've said hello. The fear of what silence might reveal about them propels their mouth to pump out sounds in effort to prevent the entry of penetrating questions.
Another thing is that now you know something about me and I still know exactly as much about you as I did before I wrote this.
