Getting here a bit late,
I write with my wife. We got started when I was ambushed at a World Con room party in Anaheim, I didn't escape until we were committed to two articles and a short story.
In the intervening years we have ended up as SFWA members, lots and lots of paid work, and a number of novels on the "submission go round".
Writers write, everything else if frosting on the cupcake.
Formal training is nice, however many successful authors never spent a day in class, for writing...
So write, then write some more, and then (you got it) get it written down. (Grin)
Regards,
Kevin
