>feel ignorant
You are fortunate in that this is something that can be remedied in any person regardless of background except for the most hopeless degenerates. Use google scholar, use the /sci/ wikia page for textbooks, read journal articles.
>feel childish
Imagine a group of men on the hunt with you, its nighttime, cold, the darkness is swallowing everything around you in a 2 meter radius, suddenly you feel a sharp pain in your lower back, one of your mates has fired a poison tipped arrow. You were a faggot, terrible at hunting, terrible at defending your tribe, you were weak, you scared the game away whenever they took you out with them. they thought best to dispose of you.
>feel scared
You have never known true fear.
