The first step involves figuring out what type of business you want to run. Too many people focus on fast profits over choosing the right idea. Although the goal is to make money, you shouldn't base your decision on profit potential alone, ignoring your interest in or compatibility with the business. It's always better to choose a business idea that you're passionate about.

Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income? Invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop. 
For example, if you buy a $100 suit… perhaps you could rent it out for $25 for the night/weekend and someone locally is interested in just a cheap rental (because they don’t need to own a suit for the one or two times per year they wear one).

I kind of “fell into” my at home business. I was a customer of their website division a few years ago. When my husband got downsized – I closed my business and started working with my current company. It’s been such a blessing to be able to stay at home (2 girls in elementary school) and help contribute to our family. When our company started another division helping non-profits with alternative funding – it was something I was passionate about. I feel very blessed to have found the real deal with my at home businesses and in the two years I’ve been with them – it all keeps getting better.
