When we think of others opinion, we lose our opinion. We feel chained. The freedom is lost. The need to impress makes our natural state suppress. No need to impress.
It should not matter what others think of you. It should matter what you think of yourself. No need to impress.
It's natural to want to impress. It gives a lift to our ego. But our ego is our weakness. Ego can destroy. No need to impress.
