…it occurs to me that I could walk into the bar I used to go to any time and order a cheeseburger and a beer and they would give it to me for a nominal fee. Absolutely nothing prevents me from going back to who I used to be a year ago. When I am at home alone again, when a “friend” has cancelled plans with me again, when I wonder if I will ever be loved again, I very often miss the taste of a beer and a late night burger. Only my own willpower stands between me and this.
What holds us to the paths we choose, in the end, is almost nothing.
