I don't care who I am

Then you're a very odd person.

I don't care who I am and I am not attached to any specific view of my self other than to try to pick the most effective tools to accomplish some core goals and values.

So you regard your 'core goals and values' to not be part of your self?

And you're really implying that you can just pick things about yourself simply as tools to accomplish your goals? I don't think I've ever met a person that can do that. Usually, there are facts about who we are and we need to work very hard to do anything about them.
