Craft a Simple Hypothesis
Put your best guess on paper: “If I do X right after Y for fourteen days, I expect Z.” Make X concrete, Y stable, and Z observable. For example, “If I drink a full glass of water immediately after making coffee for two weeks, I expect fewer afternoon headaches.” The clarity sharpens attention, keeps the experiment honest, and turns results—good or bad—into useful information that informs your next deliberate step.
