There are several things from this psychology course that I am almost certain to remember. The funny part about the memories is that they will all have one common theme: gaining and maintaining the attraction/ affection of women.
An example of one part I will remember is how emotions are formed: first someone is aroused, and then they assign that arousal to a certain emotion. This is especially useful for date ideas. I will make sure to take my date to somewhere arousing like a theme park! Another theme from psychology that is sure to help me, is the fact that people are more attracted to people with close proximity, or who they see often. This can be taken advantage of when trying to woo a girl, and I believe this is the reason that persistent boys tend to have the most girlriends!
Lastly, it is very interesting that the most attractive type of face is the most average one. I think it would be interesting for me to take advantage of this by having children (way, way in the future) with an exotic-looking girl with many ethnicities in her blood. That would allow me to have the most "average" looking children and thus the most attractive children!
