You shine more brighter thinking everyone can already see the complete obvious... When your just draining your energy away that will (sooner rather then later) exhaust ALL the light in you that's essentially shining brighter then anyone else! Potentially forcing you too see reason of what the obvious already had been giving away since the very moment you started "showing off"! PS... It is what's called when you shove everyone else out...except your very own "pretentious" ego!
Thinking you can shine brighter than anyone else is fine and all. Only when it's for a greater point, then one's very self-importance clogging the way of your seemingly random non-negotiable reasoning that set's flames full of obliviousness!
