I managed to pull out some full weeks of full-time, full-throttle work, but it is completely unsustainable. This is, social life, other activities, having out of the box solutions and ideas, friends, family are all strayed aside as secondary, weekend concerns. Work was the primary concern. That progressively led to loosing focus with other realities, lack of diversity, and all the things that brings on board.
The main point is, even if had 100% efficiency, would it matter if it was directed towards the wrong thing? A good deal of our work is to judge and be critical of how it will impact others, the world even. And sincerely, I think that it is a major problem on many companies which just fail because everyone is too busy "working", but do not collectively have the opportunity to ponder, to talk to other people, to get different perspectives, and realize as whole that the ship is going full steam ahead for the iceberg.
