Fear is a good thing, it is anxiety that is worrisome. Fear should be channelised for good things and one would experience good outcomes out of fear. I personally as a dentist Have a close encounter with Fear on daily basis (i suppose u got what i meant😛) but how you channelise that fear of oneself or anyother person is what matters more. If one fails to channel the fear, it grows into anxiety and some grey hairs are coming your way soon enough if anxiety rings your doorbell...lol
