Having some "Me time" once or twice a month. Going out, with wallet in hand and nothing else, going to the cinemas, playing at arcades, visiting a couple of spas, and having a nice cup of iced americano while listening to music at any cafe.
(Yes, i have friends but i prefer to being alone during my "me time", else i would be having trouble excusing myself if i want to go to spas for some "relaxation" 😉.)
