It's good to know who you are because I've been trying to understand who I am for over 50 years and I'm no nearer the answer. If anything, the answer to the question become more and more distant and my idea of who I am seems to be dissolving.
Everybody is different, so these are just my opinions, to be tossed away as mere ramblings or to be taken on board and reflected upon. We each have a choice, although not necessarily free will to choose.
I don't much care what people think about me because even if someone is complimentary there is no way I can know if they are telling the truth. I tell my partner that I love her, but how does she really know? She can't. She tells me she loves me and I can never know if it's really true. I simply accept that she says she does and the only thing I can do is to live with the illusion I have created that I believe she loves me. It's all just in our heads. All of reality is just in our heads.
We can't control how other people feel about us. Even the people who love us. My partner is sometimes angry and frustrated with me. Should I change who I am to accommodate her? I don't think so because the things she finds pleasant or unpleasant are always in flux. Never change to meet changes. That said, everything is always changing and the idea of security and stability is just an illusion.
So, I think you're right to say that "as long as I'm good enough for me, that's really the best I can be".
It's strange because the more I think about it, the more concrete my certainty that there is no meaning to life becomes. We have no road map for life and for happiness. Look at people like Trump in the US and Johnson in the UK. They have obtained their life goals and they don't appear to be very happy. If anything, those two examples crave adulation, not only from one person, but from millions of people. It must be like a living hell.
For me personally, I get up and try to do something positive for people. I'm not always successful. Sometimes doing a good deed brings about a bad consequence for someone. As long as your motivation is pure, as long as you're trying to be selfless, then I think peace of mind stems from this.
Just my 2 cents worth.
