I have spent some time reading /r/niceguys and it is an eye opener, especially after reading books like NMMNG and running into a number of these guys. Some of these "nice guys" in the world are clearly desperate dudes that are just lashing out because their blue pill tactics give mediocre results for a high personal investment.

Instead of trying a new path (/r/fitness, MGTOW, Red Pill, PUA) they choose to keep trying the same thing over and over again, while expecting a different result.

Do not be like these guys.
