Your point in trying to become self aware is the key here. In my experience, every reaction from people whether good or bad is based on their perception of something I've done or how I behave, mannerisms, etc.

With that being said everything is not YOUR fault either, there will always be a percentage of people that misinterpret your behavior and dislike you based on those things.

I've learned to accept that some people will be rubbed the wrong way and vice versa, that is just life. but if it seems to be happening a lot I tend to think its something in my behavior that is being misinterpreted consistently and then it's probably on me.

There is only one you can control and that is yourself. If you're being misinterpreted find out why and then see if its' something you can adjust, if not, accept that it it how it is.
