Bad Habit

I developed a bad habit the past few weeks. Something so unlike me, it actually surprised me that I was capable of it. Having recognized it, I at once decided I can no longer continue the behavior. And I also got to thinking about where it came from.
So what happened to get my panties all in a twist like this? I noticed that in a relatively short period of time there was a succession of people that I blew off. Just completely didn't follow up with on plans that were made, didnt respond to, etc.
Now in the grand scheme of things, it was maybe 4 people, none of whom I don't think would harbor any sort of resentment towards me for doing so; my sins were relatively minor. But isolating the offenses as a potential pattern made me very uncomfortable. And I think the root of the reason why is that I put a lot of effort into and take pride in being a good friend. And in that, I take making plans, investing into my relationships, and seeing my friends regularly all very seriously. Sure, everyone wants to think that they are a good friend, and really, the proof is in the pudding on that one - I am of the opinion that one must actively give of themselves in order to do so.
Others don't see friendships in the same light. This is a principle point of disagreement between T and I, in fact. And speaking generally, many people I know very much live their lives "for themselves," so canceling tentative plans because they're not up for it isn't thought about twice. In that way, most are understanding of others doing the same. But while I am forgiving of this in others (for the most part, until it becomes habitual), I am obviously not so much in myself.
So it makes me question why this started happening in the first place, and I think that I had gotten to the point that, while I was very much engaging in enjoyable activities, I wasn't giving myself enough quiet alone time (I like keeping myself busy and social, so it's not surprising to me that this happened). I reached a breaking point where my mind subconsciously forced it upon me. I think this the case because every time it happened, I wasn't off to bigger/better/cooler plans (thank god, I wouldn't be able to live with myself had that been the case - always looking for something better is a major pet peeve of mine). I just spent time tidying up, doing errands, reading, etc. I had somehow fallen off kilter with my home front, and this was my way of regaining some stability.
Now I feel back in my groove, my to do list is much shorter (although I have been putting off switching my blackberry over to the new one for at least a month, dammit!), I'm back into a routine, and I've forgiven myself for my lull in friendship manners. Reflecting on it has renewed my commitment to my investment into the people around me that I care about, which is something I'm happy about as well.
