Courage is not the absence of fear. It is fear with the legs still moving.
The clearest example is small. Somebody speaks in a meeting with their voice going unsteady on the third word, says the thing anyway, and goes slightly red for a minute afterwards. Nobody in that room files it as bravery. Everyone who has ever done it knows precisely what it cost. The fear was fully present throughout and never got a vote.
The second half of the trade is the same move made quieter — the thing done at the level available to you today, rather than not done at the level you had in mind.
