It is really important. For me, my "me" time helps me to deal with everything, from chaos to happiness. I become frustrated if I do not get my me time, and then it reflects in my disposition. And that me time not necessarily means a visit to a spa or a movie or a lunch at a restaurant, that can mean a quiet hour all to myself. Where I may be just lying on the bed and staring at the wall. Though this is not what I do, but just to emphasise that "me" time can mean the most boring thing as well.
