One of Ireland Information Guide's rules to consider:

In order to prevent prolonged disputes about the significance and factual accuracy of added material on subjects in which you are personally involved, it is often a good idea to wait until others lay the groundwork. This is especially true for auto-biographies.

If you create a new article about yourself it will most likely be listed on votes for deletion and a heavy debate will ensue. That does not mean it will be deleted, of course, but there are people who feel strongly that you should at the very least not start articles about yourself, no matter how important you consider yourself. This is because independent creation encourages independent validation both of significance and of verifiability.

If you are reasonably significant, someone will create an article about you sooner or later. You are free to contribute to that article, but please only add verifiable information and be especially careful to respect the neutral point of view.

Similar principles apply to articles about works that you are primarily responsible for — the company you run, the website you started, the paper you wrote. Use common sense.

Editing an article about yourself or your organization is also generally considered improper and best avoided, on the same principle. Noting objections or corrections on the talk page may be appropriate.

Several autobiographical articles have been a source of dismay to their original authors after a period of editing by the community, and in at least three instances have been listed for deletion by their original authors. In most cases the article is kept. Be warned.
