I've started keeping mind maps of various bits of information I collect or produce, just because it's a better way to visualise some things. Object design for programs comes particularly naturally this way for me, though to define a more solid data design I turn to ORM in Visio. Still, when my thoughts are bubbling and boiling, I feel rested after getting things down this way, and that's a sure sign that I subconsciously accept this as a valid information management option.
