The need to broadcast stems from insecurity. By marketing your lifestyle and accomplishments you are seeking approval and envy.
If you seek attention, you will find it. But attention-seeking is less about courage than insecurity.
A person who dresses or acts to court attention is not bold; they are lonely. They want to be noticed. Their performance is intended to seduce you into adopting the role of audience.
Resist the urge to parade your accomplishments. Showing-off only attracts unwanted attention in the form of jealousy and resentment.
Chuang Tzu argues that it is foolish to advertise your wealth or your fighting skills.
