Why do some people enjoy making plans?

I think people enjoy making plans because it gives them a sense of control over their time and responsibilities. As a UI designer in Shanghai, I know that without planning, my work deadlines and personal goals would feel overwhelming. For example, when I trained for that half marathon I mentioned, following a strict running schedule was the only way to balance it with my job. That said, some people take planning too far-my colleague spends hours color-coding her calendar, which actually makes her more stressed when things don't go exactly as scheduled. So planning helps, but flexibility matters too.
