Don't try to create and analyze at the same time. They're different processes.
It is not futile to do what we do. We wake up with energy and we do something. And we make, of course, failures and we make mistakes, but we sometimes get glimpses of what we might do next.
A meal without mushrooms is like a day without rain.
We need not destroy the past. It is gone.
If someone says can't, that shows you what to do.
Our intention is to affirm this life, not to bring order out of chaos, nor to suggest improvements in creation, but simply to wake up to the very life we're living, which is so excellent once one gets one's mind and desires out of its way and lets it act of it's own accord.
