This is totally possible. The general advice is to solve a problem. But to be a bit more specific, I will say the following: - Create a product in a niche and focus on finding customers within that niche. For a goal of $3000/month, it is surely possible and not too crazy - Don't just rely on yourself even though there are many 1 man success stories here on HN. I would say get at least 2-3 trusted helpers even if they are part time and slowly delegate the not so critical aspects to them while you still focus on the core. For example, if you a SAAS product, you could still do coding + customer support while you could delegate some of the other admin stuff including some customer support to someone else. This will give you leverage.
