In the high-performance world Jana and I try to play in, we know that reaching the "Summit" requires more than just grit.  It requires Atmospheric Clarity.

They start "solo grinding" instead of "shared partnering.”  Just like in nature, when water boils, the team turns into an every person (every molecule) for himself to get over the finish line.
