Why do most people not follow their bliss? One word: fear. We are overwhelmed by fear and primarily we are overwhelmed by the fear of what other people will think of us.
Joseph Campbell says "What will they think of me must be put aside for bliss."
One of the biggest inhibitors to following our bliss is "What will they think of me? Am I going to look like an idiot if I follow my bliss and I fail? Am I going to look like a fool?" -- all these different questions come into our mind.
