The hardest part of collecting wasn’t finding watches I liked. I usually did, and even when I didn’t I enjoyed the exploration. I never hankered after anything I couldn’t get. Why inject misery into something that should be exclusively pleasurable?
The hardest - and most draining - part of collecting was fending off heavy handed brand marketing, an irritatingly mendicant watch media, and group think.
To answer your question directly though: the simplest way to recharge one’s batteries is to tune out altogether and do things that give you actual pleasure instead.
