From a time angle, it doesn’t matter if we’re surfing a the highest of highs or lowest of lows, it’s still the same damn hour.
The rub is, spiritual highs/dark depressions are easy to get caught up in because they feel meaningful when in fact they are bio-chemical events that pass accordingly.
To relate this to BJJ, relax as much possible and don’t get caught up in the hype, be it emotional or cultural. And, if you do find yourself bouncing off the walls or dragging a$$, smile at yourself and either take the day off or get back to work.
Objectivity and logic are our quarry. Study and train accordingly.
