How Do You Keep the Version Straight in Your Head?

How do you keep the different versions straight in your head? For me, that's what i have to start over. That's exactly why i od get, i wo e, go ahead, mat. The names you chose in the book are really interesting. I come up with them out of thin air,. or i think about people i know, orth the children of people i work with. Sometimes i'll be reading harry potter as a family, and tracy and i will go, does that name really sound like that person? I don't think so.
