No matter where you are in your research, or what supplies you can afford, start organizing now. Don't let your notes pile up, because at some point you will get lost and all your hard work will become useless. The second rule is to set up a system where you will be able to find what you need, when you need it. That is why personalizing your system is important. If someone else's system doesn't make sense to you or seems too unwieldly, it won't work for you.
Genealogy is a very personal endeavor.
So, for whatever it is worth, here is my system. I hope you can get some ideas from it. It is a useful place to put things until I can get them into my surname binders. My binders are the center of my family information. I keep two binders for each major surname.
