@RKTansky some do, definitely. Some people may find that that works but I could never imagine doing that. Inspiration comes when you're not always searching for it, I've found.
If you feel like that would work for you you should go for a few hours of writing without any distractions. If it's not something that you'd enjoy then I wouldn't recommend it.
Perhaps professional authors do force themselves to write even when they don't feel like it - shows perseverance - but especially for someone starting out l wouldn't force it. One wouldn't want it to feel like a chore.
Yet that doesn't mean to never write when the going gets tough; sometimes I don't want to write something new so I'll tell myself to just write the opening lines of my next chapter. That way I can at least say that I wrote something. Also, if you can get yourself over the first hurdle of actually starting you'll find that eventually things will start to flow.
That's a good idea! You do need to make notes of any ideas you get as sometimes you can have so many floating about that you'll risk losing the ones that truly matter.
I think you're finding that this writing thing is actually pretty challenging. I was in for a surprise myself since I love writing essays and the like, I thought that everything else would be smooth sailing xD doesn't mean it's impossible though! You'll want to tear your hair out at times but trust me, you're making something worthwhile. :)
