I think you are who you really are, already. Discovering is about observing yourself. For example, I love to ask questions and to analyze the hell out of things. People often tell me I think too much. But I don’t. I think enough for me. I think because I enjoy figuring shit out. I think because I like to be able to explain things.
When I was young, I felt like there was something wrong with me for thinking so much. Over the years I realized that I love it, and so it doesn’t matter what anyone else says. I’ll think as much as I like. If it brings me excess angst or worry, too bad. It also makes me happy.
So watch what you do. Watch how you behave with others. Watch how you think. Especially watch when you find yourself doing something you “shouldn’t” do. Those, I believe, are key, because they show you want you do despite a lot of pressure to not do it. Like me and thinking.
It will probably take a while because you may constantly question your observations. You will constantly want to be who you think you should be instead of who you are. Like I just found out that I’ve been codependent for years. I always knew I was afraid of being alone, but I didn’t understand this model of relationships that fits me to a T. It may not be a nice thing to be or a happy thing to be, but it is definitely part of who I really am. At the moment.
Who you really are changes. Some of it is because you want to change, and some of it happens in response to circumstances and you don’t even notice it. Unless you are observing carefully. Who you are is who you are, right now. Not who you want to be. Not who you were. It’s who you are, and all you have to do is to watch and you’ll see it.
