Here is my take on that.

As a social creature, there is an intense amount of interaction that goes on in life which could involve a lot of playing different roles. For example when you are in front of your boss you act different and similar is the case when you are with your girlfriend or a teacher. These immense amount of interaction could lead into a psychological frustration and you'd feel that there is nobody on your side as you never have the chance to be yourself. This will now be manifested into a form of quest for something which you wouldn't know resulting in a troubled soul and a feeling of lack of accomplishment. Now, deep down you start to get dissatisfied and it could bifurcate into two seperate but distinct path. Either you get motivated and work hard, or you resign. If you get motivated and work hard, then with time you could still acquire your desirables but will still lead you into wandering coz by then you would still be dissatisfied despite the fact that you've gottan everything you desired as your soul still feels empty. On the other hand, if you've resigned except for whining and crying there is nothing else you could do so you would be regretful throughout your life. Both these sense of lacking is only overturned when there is someone or something that you could associate with your life, that helps to be yourself, and also that could allow you to dissociate with everything else if you chose to do so and still be happy. And that is love. In other words it could be your psychological win or a psychological surrender but will still allow you to be yourself and be happy. After all according to Mr. Aristotle our end goal is happiness. Think about the song by Beatles "bla bla bla bla bla bla bla... money cant buy me love" or even the concept of yin and yang.....
