For some, being a stickler for scheduling every activity feels rigid. But a quick look at your calendar (or reflection if you don’t keep one) reveals your priorities. You vote with your actions, not with what you claim as important.
If it feels rigid to you, just remember that YOU are in charge of your calendar. You can change it anytime to something that feels better.
The purpose of keeping a calendar and managing your time is to make sure that you allocate time for your most important items. The point then is to schedule your priorities, not just prioritize your schedule.
