I work in IT and mostly write reports for long-term projects.
I've seen a few consultants in the office that keep a "work log". They basically use a notebook with lined sheets and write down bits & pieces of information that they accumulate or generate throughout the work day.
I assume this is important in the consulting business where you must bill by the hour, but is it important and useful in the corporate life in general?
Making a work log sounds like a decent way to bring my expensive leather 3-ring binder to a useful state (after switching to the Hipster PDA!).
Do YOU keep a work log? Or a life log? How do you manage it and store it?
