That would be true... If people and time stood still, that is.
Simply put: We spend SO much time being cautious, treading lightly or playing by own rule book, we miss the fun in sometimes rolling with the punches and running with a feeling every so often.
What IF, as opposed to not stepping up to someone that catches your eye, you just let it go... Then what? You're left wondering what could have happened. And what fun is there in that?
