I personally believe we developed language because of our deep inner need to complain.

Language developed as a need for humanity to communicate, but this is not what the author conveys by means of this quote. It seems that people are misusing language to just complain about what they think is wrong, instead of shutting up and changing that thing. Listening to people complaining is noise to the world’s ears. So, be the first to use language correctly by giving voice to your inner beautiful soul.
