In my humble opinion the most important topic discussed in this class as it relates to everyday life was personality. Personally I can see myself using what I now know about personality in the future as it comes in handy whenever you meet someone new. When you first meet someone often you try to find out who they are, ie. their personality. Using the tools like the Big 5 can help draw out ones personality so one can understand them better. Knowing how the different personalities also allows one to know better how to handle someone and what makes that person tick.
Along with knowing personality, knowing the Attachment theory is something that can come in handy in the future when dealing with people. With the attachment theory it allows one to better understand a boyfriend/girlfriend and why they may act the way they do. Knowing this will put us in a better position to deal with that person and how to handle them when they may be acting a certain way.
So in conclusion knowing more about personalities and the Attachment theory will be something that we can use in the future as it helps up understand the people in our lives.
