At times in my life, I have found computer games to be a terribly compulsive way to lose whole days. I deleted the games from my computer, but would then play free internet games.
Last week, I decided to make a change. I realize it's only been a few days, but I believe the change will be permanent. I decided not to play computer games anymore. Period. It was a hard decision and I spent a bunch of time thinking it through and writing about it in my journal. In the end, I decided that for me, playing computer games doesn't add anything positive to my life and is detrimental (as a means of procrastination, as an activity that does not encourage mindfulness, as a way to develop carpal tunnel or other hand/wrist pain, etc.), and that if I am looking for enjoyable leisure activities, I know of several that actually make me feel good while I'm doing them & after (reading, listening to music, walking, talking with friends, etc.).
I have a good friend who stopped drinking almost 6 years ago, after 2 DUIs. He'd never tried to stop before. But one day it became clear to him that drinking was a problem in his life and that there was one way to make that problem go away. He's been very fortunate that he's never been tempted to drink again, even in the face of major stressors (bankruptcy, the death of his sister, loss of jobs). His example led me to believe that I, too, could give up addictive behaviors and that it needn't, necessarily, take a long time, with lots of failed attempts, etc., which is what I used to believe. Since his inspirational example, I've given up decaf coffee (admittedly a habit, not an addiction), alcohol (I had less than a drink a month, so that wasn't a big deal), and became a vegetarian (that was a big deal, though not giving up an addictive behavior or substance). His example has helped me to believe that it is possible for me to commit to making a life change and have it be permanent. Just like that.
Doing that with procrastination itself is not so easy, however.
