I think statistically managers start at about 28 for smaller companies.

I have a huge breadth of experience with projects both big and small. Also where I live, fluent English isn't so common. Also have some professional training experience.

I do blog a lot of stuff on management on Facebbook. Crazy theories and books to read, to the point of obsession, because I'm frustrated at how many projects are managed. A lot of people recruit me from there.
