Gender confusion

This blog is meant to encourage readers to share their own stories based on my posts about everday awkward living. This post may not be the case because I could be the only person who experiences this:
Once in a while I'll think about myself in the future, imagining that I've become a famous painter, filmmaker, musician, politician, or maybe even philanthropist! Sometimes I'll imagine myself being interviewed on E! Biographies or something like that. Now, it's not like I do this just so I can talk about myself in my own head, but to think about what I want to accomplish in life. It also comes up kind of subconsciously. I imagine telling my own autobiography in anticipation that if somebody asks me "Why did you choose to paint over becoming a dancer," or "What was your reason for moving to New Zealand and raising twelve children?" I would have an answer ready. It's all a bit ludicrous since I really don't know where I'll be in forty years, but that's not the craziest part!
What I don't understand is that when I imagine these interviews, I'm a sixty year old man, usually with a gray beard. Did you get that?! A MAN! Is our society so male-dominated that I can't even imagine myself as a famous WOMAN? It's kinda like when your reading an article and you automatically imagine a man wrote it until you see the author's name is something like Betty O'Connell. Except I KNOW I'm a woman!
What does this mean? Do I not see myself accomplishing anything in life so I subconsciously replace my older self with an anonymous man? Have I maybe seen too many television interviews with bearded men thus proving my male-dominated theory? Am I sexist against my own gender?
I guess this is just something I'll have to consciously change, or maybe I should just stop imagining myself in the far future since I don't even know if I'll be a single, overachieving, workaholic artist, or a family woman living on the other side of the planet with twelve little munchkins and an Australian/Filipino husband.
