On thrashing.
Overthinking, overanalyzing, over-discussing, or over-pursuit of any kind will eventually degrade the work you're trying to do. It will tax resources, create harmful disagreement, and prevent progress.
The best way to avoid thrashing is to have an objective in mind. What are we trying to do? And for whom? Why do they care about what we're trying to do?
Thinking about artists for a second - we don't really stop to think of these questions. Who is it for? It's for everyone that loves music. Is that really who it is for? Or is it for us? To record something that makes us happy and proud. So we thrash. We overthink, we stress, and we try to record some music. Just nobody knows about it. Or if they do, it's by happenstance.
I suggest "productive thrash." Productively asking questions that enable us to home in and identify our objective and our subject. Because doing that allows you to better create something worth something for someone else.
