This might sound weird but I always like taking a handheld with me when I go to work or go out for a while in general. It helps with my anxiety knowing I can play a game to calm me down even if it’s just for like 20 minutes in the bathroom. My favorites to carry are a 3DS, switch, or vita.
As a remote software dev I always have to have at least 2 if not 3 devices that can be considered handhelds, but I never play games outside my home.
