We relied on immediately gratification for a very long time. Why did we drink if we knew we'd eventually get sick or wake up feeling terrible? Immediate gratification. Unpleasant consequence came later. In a way, we felt in control of something. I'm finding now that most things that are immediately satisfying are in the long run less satisfying.
Sometimes it's great to know there's nothing to be done in this moment.. and the waiting part needn't be so hostile, it is where we should be present and focused on the now. Nothing is happening now, so I don't have to worry about anything right now.
