You’re holding a pretty complicated construct in your head. Recreating that construct a week later is hard. You have to remember all the factors that you were considering when you made that choice. You have to re-create the thought process that led you to that decision. You have to become your past self again, put yourself back inside a mind that no longer exists. Doing that takes time. A long time. Twenty-four times as long as it would take if you had fixed the problem when you first discovered it.
