The problem with people is that we were born with no ‘How To’ manual. It IS very confusing just trying to live alongside billions of other people. At best, most of humanity is just randomly existing, hoping that the combination of arbitrary actions might lead up to success. Sometimes it does, most times life is just tepid until we die.
Which is why I do not hurry to kick Life Advice in the nuts. We all need direction, and people will attempt to draw anecdotes to guide others to success. They might fail at it, but there will always remain the need for guidance.
