It can make us jealous of others' paths while simultaneously pushing us to discover our own. Watching others succeed does a funny thing to us QLC-er's (... like inventing our own words for instance). We are genuinely happy when we see our friends, family, or colleagues kicking butt in the real world and making strides in their lives. But at the same time, it can make us feel extremely insecure about what we're doing and where we are in our own lives.
We long for that same success, stability, security, confidence -- whatever it may be. We think: man, maybe I should follow in their footsteps.. they seem so happy with where they are!
