'Once bitten, twice shy.' So goes the old saying. It is rooted in great wisdom. Yet, just as a root is not the ultimate manifestation of a plant's natural potential, the saying stops short of the full message it ought to convey. Once we have been bitten by anything, we are indeed more likely to avoid the possibility of this happening again in the same way. But that doesn't mean we should now start to live in fear of any situation that happens to have some teeth. Don't let an old fear prevent positive progress today.
