Change happens when the pain of staying the same is greater than the pain of change.
For me it wasn’t until I realized that continuing to drink might be more painful than quitting could I make the decision to stop. I think we sometimes we think to far ahead and scare ourselves into not acting. I would come of with reasons and justifications like. I’ll never have any fun again, all my friends drink, it’s not that bad, it’s too hard I can’t do it etc. Eventually you get to a point where you get to a point where you just can’t do it anymore and stop making excuses. It’s a great reminder when talking to other alcoholics too because it reminds me of how hard it is to stop and when I see someone that can’t stay sober that maybe the pain isn’t great enough yet.
