I had a similar situation. I had been meaning to attend games ever since I graduated, but had just never gotten around to it. My wife ended up winning a 6-game plan in a silent auction. I have not missed a home game or post season tournament game since then.
Related to that, I am kind of an all in kind of person. When I do something, I like to do it all the way. You can see when I started attending games I did not stop. I am guessing that maybe you are similar in a way since once you started, you have not stopped going either.
On the flip side, once I stop being committed to something, it tends to go away completely pretty quickly. For example, I used to drag race in a league and many weeks was racing 3 days a week. I used to leave vacations early to ensure I never missed a race. In the off season one year, I decided that I would slow things down, not join the points and only go when I felt like it. I went one time after that and have never been back. I did not stop intentionally, but once I allowed myself the option of not doing it, I never found the time to do it again.
Related to Mason, at this moment, I don't plan on going to Brooklyn, maybe I'll change my mind at the last minute.... I have serious concerns about renewing my season tickets and donating to the Patriot Club without knowing some concrete plans/expectations regarding Hewitt and a fourth year. My fear is this, once I miss a post season tournament game or home game, maybe I lose what has been driving me to make sure I go to them all.
