1) Social interactions. This obsession with confidence mantra has nothing to do with feeling good about yourself, but is really nothing more than conformist propaganda. Most self-help is nonsense to me. Leave people alone, and they’ll naturally blossom when they realize they can be themselves without ridicule.
2) Dating rules and advice. These create more problems than they solve. Most dating advice centers around mechanical initiation methods, confining actions to the birth sex of a person, stereotyping each gender/sex and other outdated rules. These actually prevent many compatible people from meeting each other, when there’s nothing simple about human personalities.
3) Religion. Religious intolerance is the cause of a great deal of turmoil, which should be expected when one’s ‘Truth’ supersedes making the world a better place where people can peacefully co-exist with others. People should be more spiritual and less religious, and if one’s religion forces one to make others convert, they either need a more spiritually based religion, or no religion at all then.
4) Overpopulation. Why worry about this? The Earth will inevitably take care of this problem for us itself one way or another.
