I just left early from a 3-day Vipassana sitting. I sat for 2 days, and given that it has been 3 years since my initial 10-day sit, I was doing quite well, except that my mind was distracted by an upcoming move to another city, and I also had in my mind that I wanted to celebrate my birthday with my friends on saturday night (my birthday being on sunday, the end of the course). I convinced myself that 3 days wasn't enough anyway and that it wasn't doing much for me (which is a complete fabrication). Essentially, I let my desire to play take over and I left. With 1 more day to go. Once on the road I realized my mistake, and now I feel completely depressed and angry at myself for not finishing the course (a common theme in my life is getting distracted by fun, to a point where it's out of balance). I don't know what to turn to, so I thought i would see if anybody here has any advise or direction for any literature, videos, etc. to help calm myself down.
Ben's advice is sound.
I'd just add that the problem you mention is universal - we are all distracted from practice by fun, by wants of some sort or another, that's why we are here. To figure out this wanting, this neediness is a big part of practice, I think.
