I really dislike when people decide that a certain group of people, lets say INFJs, are all a certain way, like all are not complex or all are complex. We obviously all have different definitions of what 'complex' means to us.
I'm thinking that when I was 20 I would have thought I wasn't complex. I know better now. I am complex because I can adapt, I can review my beliefs when new information or new experiences come my way. I am complex because I cannot tell you how I will be in a year from now let a lone in five years or ten years. I am complex because I can view things from every perspective possible and make a different decision every time depending on circumstances. I am complex because I'm still trying to figure out all the different layers of feelings and thoughts that can come up during different life experiences. I am complex because I don't judge a person at face value or label them according to my personal experience but can take into consideration the situation and view people and their environment in a holistic manner so as not to put them in these little neat boxes of what I think they are but am open to them surprising me or showing me different facets of themselves that is not so obvious.
I don't go around telling people that I am complex. I'm the only person that knows how complex I am. I am straightforward and honest and have strong beliefs about certain things and those things might make people believe that I am simple to figure out but nobody really knows me because I do not share with others all that goes on in my head and in my heart. It would probably just complicate things with the people around me if I shared all of that so I keep it simple for them most of the time. In recent years I have definitely really surprised many people. I've even surprised myself.
I think everybody is complex to a certain degree but I have a feeling that I am more so than most people around me, although maybe I'm not. I don't think being complex is necessarily a good thing because it can really bog you down, but at the same time it can open you up to a lot more possibilities than if you limit yourself to a simple way of thinking about everything. It all depends on how you handle it and how you learn from your experiences.
