Question: how can one manage not to lose time? Answer: experience it at its full length. Means: spend days in the dentist's waiting room on an uncomfortable chair; live on one's balcony on a Sunday afternoon; listen to lectures in a language that one does not understand, choose the most roundabout and least convenient routes on the railway (and, naturally, travel standing up); queue at the box-office for theatres and so on and not take one's seat; etc.
