Passion gets pictured as fire: sudden, hot, total. Most of it looks like a novel written in twenty-minute blocks before a shift, four hundred words at a time, for six years.
Dedication is what happens on the days the feeling isn't there. The feeling comes and goes. The twenty minutes can stay.
Underneath sits a quieter question: which passions get your best hours, and which get whatever survives everything else. That answer shapes what you become more than any declaration does.
