Interesting the title says you don't use it often, but the text says you use if often.
I personally let mine sleep when I am not using it. It is plugged in all the time to maintain power, take it off the power to use it unless it is for all day video calls, then I plug it in to guarantee the battery will not run out before the day is done.
Also in sleep mode the Macbook can wake up on its own to do updates when you are not using it if it is a 2016 Macbook pro or later.
