Unless they are living their personal dream and telling you all about their personal adventures and how they themselves alone turned themselves alone into a "success story" all alone with no outside help from anybody but their own hand and sweat, then they are leaving a few things out. Nobody does anything alone. You can be completely broke and out of touch alone. You can be a total drunk alone. You can be in a relationship alone. But nobody does anything or becomes anything... alone. The issue is that people either grow apart or hang on to something that was never really there to begin with.
