Honestly, I just jumped in feet-first and did what I loved. I was knee-deep in Desktop Publishing for organizations and my workplace... I studied Education & Interpretation in college, which included some design & usability principles material. I practiced, experimented, saw what worked and kept doing the good stuff. Kept taking on new projects, kept my ear to the wind, relied on word-of-mouth referrals.
The owner of our local print shop, which also produces a weekly shopper (newspaper/advertising paper) saw my work, liked it, and tapped me for some writing and layout work when he needed a hand. I met people and was recommended by people who knew people, through just a handful of gigs for the printer.
I have had a lot of fun thinking up & designing ads, newsletters, brochures, promos, signs, etc. for my gift shop, which I bought 10 years ago. However the days of one-job-for-50-years are long gone, the name of the game now is to
diversify. I learned about web hosting through several disasters with my gift shop's website, got doggone PO'd and decided to just learn the biz and do the hosting myself, so "it'd be done right." At least then if it got screwed up, it'd be my own fault, right? Heh! Well we are all strong-headed self-starters here, we know how that goes!!!
That was six years ago

and it's amazing to me how business has grown and changed since then... but I still love it and I am adamantly sticking to the original principle of
doing it right no matter the size or scope of the business. Might be bigger, but bigger isn't necessarily better. Just like in marketing, time-tested principles (such as "quality over quantity") stay the same, remain as true as ever.
The thing about pre-internet vs. internet, is that at least for me, my upstream hasn't really changed. Word-of-mouth is still my #1 source of new business ,both for my gift shop's website and for the web hosting biz. I've long since learned that if you do right by people, they will be happy to recommend you... and when it comes down to it, a personal recommendation, and the trust that it rides upon, is hands-down
the most valuable advertisement out there.
So the media has changed, but the mechanisms have not. At least for me.
