Everyone is an individual. What that means is that you are unique. Just because people dress alike or eat at the same place, does not mean that they are all the same. Though I do understand that some people will do anything to try and fit in and be like the norm.
Well, the truth is that there are just some people out there that don’t fit in. They are who they are and they are not ashamed of it. It is okay to be an individual. I know that many people may make you feel like it isn't but you are allowed to be yourself. It is okay to walk to the beat of your own drum, it is okay to dress in a way that makes you feel comfortable, it is okay to listen to the music you want to listen to and it is okay to think the way that you do (as long as you are not hurting anyone or anything, of course).
I have had people try and change me all my life and to be honest, trying to please everyone all the time is not worth it and you waste far too much energy in the process. Just be yourself and those people who are worthy, will give you a chance and will accept you for who you are. Those who don’t, well, don’t worry about them, as their opinion or acceptance is not worth wasting your time on anyway.
