If there's one thing I remember well it's relationships and behaviours(probably the same for most engineers). This is distinct from what I would call knowledge

If there's one thing I remember well it's relationships and behaviours(probably the same for most engineers). This is distinct from what I would call knowledge (i.e. when something happened). For me inspiration always seems to come from comparing relationships and behaviours, memorizing information rotely doesn't contribute to this at all.
