Politeness is the first thing people lose once they get the power.
He who makes fun of a short and fat manβs weight is much less cruel than he who makes fun of his height.
Whatever negative things people think and say about you is enough to bring you down provided you belief that it carries a weight that can push you hard. Don't agree to accept what critics say; be prepared to silence them by doing what they think you can't do!
Constantly stopping to explain oneself may expand into a frustrating burden for the rare individual, so ceasing to do so is like finally dropping the weights and sprinting towards his goals. Those who insincerely misunderstand, who intentionally distort the motives of a pure-intentioned individual, then, no longer have the opportunity to block his path; instead, they are the ones left to stand on the sidelines shouting frustratedly in the wind of his trail.
