Leave enough time for a careful decision to remain careful.

Care is not only an intention, it is a condition. Squeeze the calendar and even a person who fully means to think something through will choose by reflex, because there is no room left to check anything or to change their mind. Deadlines quietly decide the quality of the reasoning that meets them, and the choice made at midnight is rarely the one that was planned.

Look at the decision ahead of you and work backwards from when it must be made. Book the thinking time as though it were a meeting with somebody else. If the slack is not there, move the deadline before it moves your judgment.
