I'm interested in hearing about how other freelancers who practice GTD structure their work time. I need a high degree of structure to be productive during the hours I have set aside for work (usually the time my son is in school) and often find myself "reverting" to a scheduled to-do list sort of thing to give myself direction for the day. I work solo from home and have few interruptions, so in many ways my time is mine to do with as I please (deadlines notwithstanding).

I would appreciate any insights or advice! Many thanks.
