If you do post, I would suggest limiting posts that mostly talk about yourself and contain little information that is of general interest. I suggest focusing on the question “how can I add value to others”.
I actually disagree with this, and so does the LW team. From the FAQ:
What can I post on LessWrong?
Posts on practically any topic are welcomed on LessWrong. I (and others on the team) feel it is important that members are able to “bring their entire selves” to LessWrong and are able to share all their thoughts, ideas, and experiences without fearing whether they are “on topic” for LessWrong. Rationality is not restricted to only specific domains of one’s life and neither should LessWrong be.
However, to maintain its overall focus while still allowing posts on any topic, LessWrong classifies posts as either Personal blogposts or as Frontpage posts. See more in the post on Personal Blogpost vs Frontpage Posts.

I rarely write about myself but when I do the posts tend to be better received than usual.
