Maybe I can help. I got my BA (4 years state college) in art - Took Fine and Graphic (we called it commercial art then) , taught for a while (family expectation) , then went back to school ('95) when the digital era was dawning. Since then, I've worked mostly in advertising design, for newspapers and magazines. It was a safe, 9-5 with benefits, but those jobs were going away, so I started freelancing from home,
I'd say my biggest achievement, is just being able to say that I can keep freelance work ongoing and make a living at it. You have to juggle multiple jobs, and stay focused and creative at work and keep the business end of things going, invoicing, pricing etc.
As far as writing, in my freelance work, I worked almost exclusively with people at a distance. Email, telephone, text, all necessary to communicate, and therefore, it is necessary to be competent at writing. A lot of text comes in with typos, gramatical errors, either purely by accident, or by those whose grammar and spelling isn't the greatest, so I good command of spelling and grammar is necessary. Most of my incoming work is email, and if directions aren't clear, I pick up the phone and call.
There's a bit of a difference between designing for print and web. My focus was on print, and while print is NOT DEAD, most jobs require a knowledge of both.
These days, I've had more opportunity in Photography, so I've taken a bit of a side track in that direction, but I still output one magazine each month.
