I'm actually the opposite. I don't like when I have nothing to do. Well I shouldn't say I don't like it, but it gets boring very quickly if there is nothing to do.
I have a lot of hobbies and do a lot of "stuff" in general so I very rarely have nothing to do, which is good for me.
My favorite time to do nothing is when I go on vacation and can recharge. There's nothing more relaxing than chilling on a beach with a drink in your hand and just relaxing for a few hours while sipping drinks. But then again, I'm typically doing stuff even there such as snorkeling or playing with my son. But I definitely make a point to just sit, relax, sip, and do nothing.
