I know that feeling. I bought a bunch of blank books a while bk that I plan on putting info from books into. But I have yet to know where to start, lol. Worse case, use a normal 3ring binder and looseleaf paper, then just put more as you want/need. And when you want to make something permenate that you like, just copy it all down into the other book(the one w/o binders).
I figure this way not only do you then have two copies, but you can also store one away as a more permanate book, as well as have a chance to look bk on your work and make any edits as need be(granit edits can be done any time, just this gives you one nice and clean version).
Another thing you might try, is a digiatl book. This can be done in two ways(that I can think of right now). The first being a Microsoft Word document, where you just add what you want in pages, putting a page breaker in between if you want. Then if you ever want to, you can always just print things out. Of course this may seem less personal, but can be handy for some.
The other, is means like the above, but instead of everything in one file or such, instead make many files(all labeled accordingly) and making different folders to organize thigns. If you are good with organization and can remember where you put things this works well, if not then this will probably just confuse you more, lol.
Hope that helps,
