This chart punches you in the face with a simple truth: the green dot wins. One project gets almost all the progress. Stack on more projects and your progress per project falls off a cliff. The orange curve, dabbling, feels busy but goes nowhere. Real progress lives at x = 1.
The vertical axis is actual progress per project. The horizontal axis is how many things you are trying to juggle right now. At one project, the dot is high and happy. At two, three, seven projects, your effort gets sliced into useless little slivers. Focus and succeed, or dabble and stall.
