Sometimes, it is only when we find ourselves peering over the edge of a cliff that we realise we have no wings. We may only be inches away from stepping into an inferno before we become able to concede that we are not fireproof. Indeed, there are times when we find ourselves right at the edge, yet gloriously oblivious to the fact that we are at an edge of any kind. There is a big difference between thinking about doing something and actually doing it. An awareness of a distinction comes just in the nick of time.
