The people who know themselves best usually think about themselves the least. They did the homework already.

Self-knowledge tends to reduce self-focus rather than increase it. Once you have a reasonable sense of how you work, there is less to keep checking, so the attention that went into monitoring yourself is freed up for other people and for whatever is in front of you. Constant self-examination is usually a sign the question is still open.

Do the thinking deliberately and then let it rest. Set aside a proper hour rather than running a low background commentary all day. The aim is not to think about yourself more beautifully. It is to settle the matter enough to look outward.
