Mostly agree, however for a guy who hasn't actually divorced and handed his life responsibilities downstream to some other shmuck to deploy, 8x40 hour work week is unsustainable. You need the late shift occasionally. Precise estimates? Heh. Get real. We estimate continuously all the time otherwise we couldn't do anything, just not about the things mgmt cares about. The need for estimates is created by the fictional role of "uninvolved bystanders", also known as Management, or Customers. Mgmt's role is to create loops and count beans WRT those loops, but not for me to spoon feed them their own estimates...
