Writing, unless you target journalism and then move on, isn't something that career counselors take seriously in general as far as I know. You have to be really good, really lucky, or really original to do well and make it exclusively as a writer. I don't think anyone buys poetry these days.

My take is that writing seems "for girls" because stereotypical careers "for girls" are undervalued already, and the traditional career of being the full time parent isn't compensated at all. Writing while you're stuck with part time low wage jobs or raising kids seems like a step up, not a step down.

Besides, writing is considered so "for girls" that they are even recognized far less. Going through lists of recipients for the international awards listed here and looking at just the last 10 recipients, 3/10 nobel laurates in literature have been women, 1/10 Golden Wreath of Struga Poetry Evenings recipients, 3/10 of Neustadt International Prize for Literature recipients, 0/10 America Award in Literature recipients, 0/10 of Franz Kafka Prize recipients, 2/6 of Man Booker International Prize recipients. I can't say I see any of the mass consumer writers anywhere in there.

So hey, when you do become a writer, you'll get to use your real full name, get better responses from publishers (and won't have to submit to anywhere near as many), get paid better, and have a better chance of winning awards. And unless you for some reason choose to write smutty unhealthy romances for mills and boon, or supernatural abusive teenager relationships, or porny fanfic about emotionally manipulative BDSM afficianado millionaires, you'll even be considered "high-brow".
