People are lonely because they build walls instead of bridges. Arrogance is one such wall. It does not help in winning people or making friends. Like rust on the iron curtain it also manages to succinctly take away existing social support. What remains is a lonely person. Success breeds arrogance and that is the reason people on top sometimes end up being all alone.
