Wikipedia's policy is to not allow original ideas or opinions, even if it's from the subject of the article. This is fairly uncontroversial compared to some of the other things, like restricting edits to logged-in users.
Unless the information is clearly (1) false or (2) not in a neutral point of view, then it's perfectly good information about the subject.
Now, I don't run wikipedia, but thankfully the people who do run wikipedia happen to agree with me on this point and decided long ago that only notable and verifiable information would be included. I'm really not sure why people continue to argue the other way.
Besides, who's gonna verify all the information I write about myself?
