How do you keep yourself organized?

[Michael Johnson]

Hey BP, I working on getting my first property. I have started making calls to for sale by owners. Now I am doing some homework on the properties. I just going one step at a time. But I am curious, 

1. How do you keep from losing missed calls that dont leave voicemails.

2. Keep information on different properties separate.

I mean it really shouldnt be that hard, just keep seperate folders, or pages, but like I said I'm just starting to pick up momentum. I might as well see if I can start out with some systems. Feel free to answer however you'd like. Thanks in advance!
