Head OR Tail?

So what do lizards do when they want to escape the clutches of death and danger? They cut away their own tails, scamper away and escape unscathed.

This is what some of us should learn to do. In order to save our lives and sanity, we should cut away our "tails" (figuratively) Yes, it will hurt. But because of that sacrifice, we manage to survive and eventually, a new "tail" will grow.

However, please note that before cutting away that "tail" of yours, you should make sure that is is just a "tail" and NOT the "head". Because without your "tail", you can live, but without your "head", you will perish immediately.

So which is your tail, which is your head?
