Humans are social animals, we need connections and crave social time. Sure, everybody has their own, different capacity for spending time with other, but, in general, we all need some connection.
Some people like to think that they are free, not bound, exploratory. That they don't belong to anybody else, roaming this world completely freely. While surely it is possible to not maintain any connections, we all belong somewhere. To our family, to a group of fans of a particular band, to our high school class. We all have connections that cannot be cut.
Knowing your people, loving your people, supporting your people is the best thing there is in this life. Doing it will give you the fuel for everything else, a force one simply cannot wield otherwise.
Belong, make the world a better place.
