I love this forum, but at times I've been addicted to it, especially when I first began my copywriting business last summer.
Recently, someone commented to me that I hadn't been posting much lately and asked if my absence has been because I've been working a lot. Yes!

It's a good problem to have, but I do miss the comraderie of other writers when I'm away.
I did discover, like you have Ken, that posting on forums can steal away a lot of productivity time. When I first joined the board, I was learning EVERYTHING and discovered that I spent literally hours each evening reading and replying to posts. I discovered that although there is a wealth of information here, the best thing to do is to just get busy and start working.
When I get a free moment (like now) or when I need to rely on the expert advice of others, I still come back to this forum to learn. It's a great place to visit, but living here (like I used to) is not a good idea if you're serious about making a living as a copywriter.
The best advice I got came from Stephen Davies, and I continue to pass it on: Spend a month reading and learning everything you can, and then go out there and just do it.
