Do you have a way of working out how much you estimate a new project / website will make? I mean how do you know whether a project is going to be worthwhile spending time and money on or do you not know until it's up and running and actually making money? Anyone got any advice on this. It's something I'm struggling with. I have various ideas for projects but I don't know how to estimate how much they might make, so I'm unsure what project to focus on. How do you make these decisions?
