Anyone can do it.
Just work yourself into an existing article.
Then a couple of weeks later, start editing your page.
That said, you will be deleted pretty quickly for not being 'notable' enough.
if you get yourself in the media for something though, you can be there.
Make sure that you have multiple independent (preferably) large media references that can be used as sources on wikipedia.
Above all, don't write your entire entry like a puff piece.
Start with just one paragraph. Then get more entries in mainstream media. As these are published, add to your profile.
Write a book. Or get one ghost written. Publish it ... proper publishing with ISBN number and so forth.
And whatever you do, do not link to your own site. Ever. At least not for a long while.
