Not like anyone needs my approval, but a lot of us here do this IM thing full-time. It's a business and we rely on it to pay the bills, keep a roof over our loved ones' heads, etc. But I sometimes think we give short shrift to those who have jobs they are comfortable keeping and just want to earn a few extra bucks in their spare time. That's a completely valid reason for getting into online marketing. It's how I started way back when. It's smart, actually. Keep the steady reliable income while you learn the ropes and get your feet wet. If you want to take it to the next level, at least then you can make that decision without the added pressure of do-or-die. You'll be more likely to make a reasoned decision instead of throwing the Hail Mary pass.
So... Here's to all of you who work somewhere and do IM part-time! You rock!
If you're looking for recommendations for making the most of your part-time hours, I suggest list building and marketing (of course!) and niche affiliate marketing. Focus on one of those to the exclusion of pretty much everything else because you just don't have the time to dabble and play around. I'm not saying you have to stick with either one, but I like each because when they start working you'll find that you only have to put in maintenance time and not so much time developing things. Get good at list building and marketing, for example, and eventually you could make a few hundred bucks extra a week literally working no more than an hour or two each week.
