You may be tempted to keep adjusting a plan that is already good enough. Today rewards completion more than perfection. Finish the task, send the message, make the appointment, or close the loop before you create three more improvements that nobody asked for.
Your mind may also be sharper about other people's inconsistencies than your own limits. Be careful not to overcommit simply because you know you could do something well. Leave room in the day for rest and basic maintenance. Protecting your time is not laziness. It is what keeps your useful energy from turning into resentment.
