Personality: Videos/ Blog reading

All of the videos/ blog post had to do with personality, and things that affect how you interact and how confident you are. the first video talked about how your confidence is based on your body language and if you force your self to use open body language you can become more confident. the second video talked about how siblings affect ones personality. they are affected by if the parents pick favorites and how the parents treat different  children.the blog is just stating facts about 2 opposite personality types, in hopes that one will then understand the other better. all of these posts basically told me that ones personality is based on the different experiences in that persons life. Every person reacts a different way in a situation but the way they react is also based on they're experience during that day or from past experiences.  so in a way your personality is not set but at the same time it is set (if that makes any sense to anyone else) personally my personality has changed tremendously through out my life, though i am still quiet now, I know how to act confident and depending on the situation can actually feel confident and outgoing on many different occasions, and have many friends now. where, when i was in high school and junior high, I was completely anti social and had basically no friends. But, basically ones personality is a very difficult thing to understand, because each person reacts differently to certain things which may or may not affect their personality.
