I do have different packs for different things, but I never leave any thing inside my packs when I am at home, especially my sleeping bags. I usually use a "check list" that makes sure that every thing that I need on any given trip goes with me when I leave, so that I do do not forget any thing. Well I use the same sort of system for taking the my gear out of the pack that I use for putting it in. That way I can inspect every thing and make sure that it is in good working order before I have to worry about the next time. You know, alcohol bottles filled, new batteries put in electronics or whatever needs to be done.. If I have a piece of gear that is not functioning properly I either start to use it as a spare or use it for something else and replace it, or, if it does not work at all, just dispose of it and replace it..

The first step that you take will be one of those that get you there....
