To be honest, I think a lot of people new to photography think that they can enter into stock photography so that they don't have to commit to shooting an event. They think they can just go out and snap random pictures and make some money - one picture at a time. Once you start shooting quite a bit, and end up liking the things you shoot, then you'll become more comfortable with the idea of meeting a mom in the park with her kids, or doing some other outdoor portraits for people. If you like photography, then work on your photography skills and market yourself. If you like the idea of making a lot of residual income, then I'd strongly suggest you find a different market that isn't already overly saturated.
