Add up all of your monthly needs (no cable or movies, needs only) and then double it. (This is me being random, it's a key ratio in financial planning. 50% to your needs, 30% to wants, and 20% to savings.) At $1 per subscriber per month, you need that many subscribers. Good so far?
Now set a date that you'd like to live off of your internet income. Figure out how many days away that is, and divide the number of subscribers you need by the number of days. That's how many subscribers per day you want to have.
Now either find a PLR report, or create one for your niche. Put up a squeeze page, and write one article a day. Submit the article to Ezinearticles, and when it is published resubmit it to article dashboard, articlesalley, easyarticles, article base, and go articles (submit to more if you have the time, this is minimum).
As you make money, make your life easier. Purchase Market Samurai or MNF, and start building an actual site. If you want to make this really easy, get 2 months ahead with an autoresponder sequence for your list. Just send out a blast every two weeks or so (making sure they get plenty of quality content emails), and you're golden.
No more excuses, go get started. All the set up should take 1-2 weeks at most, and writing one article at day should take no more than 30 minutes. Get a headset and use speech recognition, an article will take you five minutes. Just get started! PM me if you have any questions.
