In the preface to his pointedly titled Unreliable Memoirs, critic Clive James laid out his approach to writing about oneself:

Most first novels are disguised autobiographies. This autobiography is a disguised novel. . . . So really the whole affair is a figment got up to sound like truth. All you can be sure of is one thing: careful as I have been to spare other people’s feelings, I have been even more careful not to spare my own. Up, that is, of course, to a point…

You want to be honest with the reader. That’s where the good stuff is. But at the same time, remember to hold things back. That’s where the artistry is. It’s a memoir, not therapy.
