You is who you always are, whatever aspects added or removed.

However weak you are, accept it. Whatever shortcomings you feel you've got, acknowledge them. You are one, and your weaknesses are things that you can work on, you are still you, you still ARE, no matter how weak or strong you are. No matter how sociable or smart you may or may not be. There is a you, and then there are all these things you can choose to work on, put your attention to. You may want to become better at playing the piano. However good you play it, or however bad, what stays the same? You. A you that is always changing. For better or for worse. ALL the things you can think of, are loose. Nothings definite. Every thing you could think of that you can like or dislike, none of these say anything about what you are. You are the one that can like or dislike, that can learn to play the piano, that can practice on becoming a social genius. The one who can do anything or nothing of those things. The base, the root of any liking or disliking. You think you get this? Dig deeper.
