Always like to talk about this topic because I'm so glad that I've chosen the right profession.
I am a freelance journalist. I chose to write for a living because thats all I ever did as a kid. First wrote comic books, then stories on an old school type writer, then made my own magazines.
I also loved to play games and read a lot of gaming magazines (before the internet arrived). Somehow though I never made the connection that I should become a journalist, so I studied for design (photoshop, illustrator, flash). While I was getting my degree for that it finally clicked with me that my passion was writing, so after I got my degree I started learning for journalism.
Ended up with an internship for one of the largest gamesites in the Netherlands and had the luck (and of course the passion, its only part luck) to get a full time gig there after graduating. Worked there for nine years, worked my way up as editor in chief. Last year I realised I started resenting the work thanks to being more occupied with the business / coördination side of things instead of writing (which is logical in the position I had), plus I travelled 5 hours each day so that didn't help either.
So this year I became a hired gun. Writing for all sorts of publications, about games but also about other stuff. While it was a scary descision, I couldn't be happier. I make enough money thank god, get new clients every once and then, I do what I love (write) and I do it mostly from home, which is also nice.
Truly, couldn't be happier with the current situation. Zero feeling of stress, lots of creativity, doing what I love... sometimes you just have to take a risk to get the life you always wanted.
