That’s mostly it from experience. There is so much unproductive churn these days it’s unreal. And that comes from the tech we use and the processes around it which are just a giant cargo cult.
Work out what you can salvage from it, salvage it, and walk for a smaller or at least different company. That’s all I can suggest.
One thing I have learned is that if you’re not happy, don’t keep doing it. It’s not worth it.
