This is one of my biggest pet peeves. I've abandoned a project because my non-tech partner constantly came up with new ideas why we couldn't launch and that we needed more features before we launched. This resulted in me being highly demotivated and frustrated.
It was all planned out and I myself had a clear path outlined but if your partner is supposed to do the marketing and PR and simply refuses to start with it, what are you going to do?
That's the other big piece of any business: buy in. You can have the best project roadmap in the world but if everyone else acts like it doesn't exist it's not very helpful!
