Ever wondered why you have the friends you do? You choose to be around people who you like, but are they really who you think they are? We often believe they are a certain way and create an idea of them in our head and then when they fail to live up to that we feel disappointed, even though they never claimed to be who you wanted them to be, that was just your own perception of them in your own head.
It could be really difficult to view people for who they really are, this is because when we come across people, talk to them, get close, we tend to associate and bind them with our expectations of them subconsciously and sometimes even consciously ignore parts of them which don't resonate well with us.
We perceive people in a very unique way, and it is subjective, it is shaped by our circumstances and beliefs.
Similarly we have an image of our own-self in our heads which is our perception of how others perceive us, it could be, and usually is very different than how others see us. It is important to understand that each one of us is unique and have our own filters and screens to go about life, which is why we should be as adapting and kind to everyone, especially our own-selves.
Changing your perspective towards people and life does impact your perspective of self, and vice versa. This could get really confusing at times especially when you fail to see your self clearly or start losing sense of self, we often do become projections of people we are around, people we admire and often lose touch with who we used to be, or who we are supposed to be. Now obviously we cannot always be the same, somethings remain constant other things change with time.
I believe it is okay to choose what you hold onto and what you let go of, although it can get overwhelming sometimes, I hope we settle in who we are someday.
