This is why i always tell my daughter, you not truly a complete person in touch with yourself unless you can be happy in a room by yourself all day.
problem is society does it's very best to try and make people feel the opposite, tells you that isolated hobbies like playing a video game, or reading a book/comicbook, watching tv, listening to music, whatever it may be is bad for you. say that you are being anti social.even use isolation as punishment to further reinforce this weakness. I can enjoy time to myself just as much as i enjoy company, has nothing to do with being anti social. some people are too reliant on others to be happy.
