Maybe it doesn't feel right. You are exposing yourself, admitting you aren't sure about things. Especially when everyone around you is loud, proud, big, bold, confident, willing to smack you over the head with their opinions.
Human Beings hate MYSTERY. But, of course, MYSTERY is everywhere.
If you look hard enough, the loudest opinion-wielders are usually the ones who know the least. That is some rule right there. Loudest talker, more sure opinion-maker is almost for sure the one who really has no idea what they are talking about.
Good rule of thumb: You don't have to know everything. And if you think you do know everything, you almost for sure are full of B.S. Yes. Indeed.
