Margen
Haste doesn't save time: it advances it. And everything that is advanced is paid back, sooner or later, with interest.
We run convinced that we are gaining minutes, but we are only moving them somewhere else. The email sent half-finished comes back as a whole afternoon of apologies. The decision taken standing up sits down afterwards for weeks. The shortcut charges its toll at the end of the road, not at the start.
Whoever goes slowly doesn't miss the train: they learn to read the timetables. And they discover that hardly any train was theirs.
