Simply, a precept to always "Leave Shit Alone" -- A concept enumerating the fact that things don't break unless they are messed with first. Normally applied to computers. People like to tweak settings, install unneeded tools, etc. But the LSA Rule can be applied to many other things in the world. See murphy's law.
