I've been tracking my deep work hours for three months now, and the days I start with a clear written plan beat my spontaneous days by at least 40% in output. Yet whenever I tell friends this, they insist that rigid planning kills their creativity. Is strict time-blocking actually more effective than going with the flow, or are we just fooling ourselves into feeling productive? I'm genuinely torn because I've seen both approaches work for different people, but my data keeps pointing one way.
