So, similarly there has to be a point when you should know to stop and simply take action. Because if you don't know exactly when to stop you end up in an infinite loop to learn and keep learning the same rehashed materials over and over again.
After studying self-help books for over four years now I feel that I have enough knowledge and experience I need to take care of myself emotionally, physically, and mentally.
By the way I'm not suggesting that you completely stop reading the materials but there has to be a balance between the amount of time you spend learning and the amount of time you spend doing.
So when will you know you studied enough self-improvement materials?
