I kind of went through the same thing when I started meditating. I tried to do it twice a day, every day for twenty minutes, which I did, yet, when things come up, things come up. So, now, my theory is, when feel like doing it, or when I think it might help, I try it. If I can't sit still, then I give up - I probably need to be doing something else anyway. Learning about meditation, was more of learning another tool to add to the ones I already have as I see it now. Same thing with meditative writing as I still do a la Natalie Goldberg. If anything, meditation is about learning to listen to yourself, so I try to follow that when deciding whether to meditate or do whatever it is I am doing.
P.S. I went to see "Latido Negro" at the Gala Theatre in D.C. recently. I learned about it at the last minute, and it was the last weekend, otherwise I would have mentioned it to you. See galatheatre.org if you are not familiar with it. Take care - Sebastian
