I am getting married in less than a month, and I just realized that the wedding is probably the Schelling point event of my life. Therefore, if I were to make a commitment to change something about myself, now is probably the time to do it. It seems to me that If I want to make a short term resolution to change something about myself, I should start on New Years Day, so that I can have that extra push of being able to say "I have not done X this year." However, If I want to make a long term change, the best time to do it is probably the wedding, since it is probably the Schelling point of events in my life.

So what are some useful commitments I can make in this once-in-a-lifetime opportunity?

One idea is to get a "Precommitment Journal", and commit to follow anything that I write down in there, but in that case, I have technically followed everything I have written in that non-existent journal, so that commitment does not really need a Schelling point start date.
