Trading is actually a physical game. Playing the “sport” of trading should be handled as if you are the quarterback of an American football team.
Rest: Being well-rested is an edge.
Diet: When one really concentrates, the body and brain use an inordinate amount of energy. Eating properly keeps your energy up and adds to that physical-psychological edge.
Exercise: Exercise gives us a physical boost that makes us feel more optimistic, and that counts as psychological capital.
The body counts essentially as much as your intellect. If the body is feeling the static of tired or drained, the feelings and emotions of risk-management and people reading can’t properly communicate their data.
