To be more specific, let’s say you decide that all club girls are bitches. There may be legitimate problems you have and legitimate factors you could be improving. You may need to dress better, speak louder, stand up straighter, and be more confident and less invested on the approach. But the second you say, “See, club girls are just bitches,” you remove all responsibility for improvement from yourself. It’s a cop-out and a way of protecting the status quo and your current level of investment.
It’s a way of shirking personal responsibility, and when you shirk personal responsibility, you never improve, you never become more vulnerable, you never become less needy.
