Thanks - that's pretty much what I was missing. And if I'm starting from scratch, what should I focus on first, and what are the most common mistakes people make at the very beginning?

I launched a small project and realized there are so many ways to promote it, but choosing just one turned out to be difficult. I started reading about online business promotion, but there’s so much information out there that it only made it harder to decide. What would you recommend focusing on right from the start so I don’t waste my time?
