Well, I'm glad you feel that way! I think writing, especially poetry, is highly psychological. The more frequently I write, sometimes the more critical I become of it. I start getting so close to the process that I become myopic and unable to see the forest for the trees at times.
The subtractive process you're talking about is something I'd like to use more. It feels quite nice once you get used to it. I tend to write in a more contemplative way, one line at a time, which is nice but also frustrating when you hit a block. Generating lots of text without needing it to be "final" can help get past those obstacles, I find.
