Team is about as close as I have been to a tribe, but they rarely last. My family is another tribe altogether but that doesn't really count.
To address my modern affliction I sought modern medicine: bought a book, watched a series on TV, YouTubed tribes and even joined tribes online. It only made matters worse. I felt more tribeless than ever.
Of late, my feelings of tribelessness are relieved by fleeting but increasingly frequent sensations of belonging to a larger tribe that is all around me. I don't want to name or brand it for fear it might disappear, but it's great to be part of it.
