Accepting criticism is not living on others' opinions

Closing your ears to all criticism prevents learning. Giving every opinion the power to change your mood or your direction makes you dependent. Between both extremes lies listening with good judgment. You can ask who is speaking, what facts they know, and whether they offer something concrete. An observation from someone trustworthy deserves more attention than an anonymous or self-serving comment. Even then, you examine it without obeying automatically. Then you decide what to do and let go of the rest. Useful criticism becomes change; unfair criticism becomes an opportunity for patience or clarification. Your peace does not require everyone to approve, but your maturity does not need to pretend that no outside perspective can teach you anything.
