How are people going to find out about it?
It's tempting to only start thinking about it once it's done.
And it's even more tempting to tell yourself that it's going to be so good that it's going to take care of itself.
The only problem is that it doesn't.
People won't magically find out about it.
No matter how good it is.
It's just too crowded out there.
"How are people going to find out about it?" is probably the most important thing to figure out.
Maybe even more important than the thing you're actually thinking about creating...
