I don't think anyone here really plans anything. I think most of us have very rough "plans", but nothing down to the details. Just like, an idea of where we want to take things. So, I can't really talk considering I still haven't posted myself, but you shouldn't really be planning that hard. I mean, if you want, you can. But over-planning stuff isn't necessarily the way to do things right or whatever. If you start to plan things out too much, you might just end up tiring yourself out. It might be better to just have fun with whatever you're doing. Be what GRRM calls a "gardener". Plant a few seeds and then just roll with whatever sprouts from them, doing things in a more reactionary fashion as you go, instead of laying every detail down like an "architect".
