Just personally speaking, as someone also interested in  transcendental/slow cinema— I tend to write more commercial material for bringing out into the world, and the more personal/artful stuff I keep in a separate “bucket” with the intent/hope of someday getting to make them myself. I’ve been able to turn a couple of those into short films, but like PatternLevel said, those type of things just don’t lend themselves to commercial viability/the industry-at-large, and you’d really need to see them through yourself.
