What have sourdough, BJJ, a career in technology, and life got in common?

Nothing… nothing other than understanding variables.

Temperature and humility change how flour acts and how yeast matures. Your opponents hips or shoulders can turn your attack into what gets you submitted. No two networks are ever the same even if the data looks identical. No one has figured out life.

The thread that runs between all of these is knowing how to change — when may be out of your control.
