I have four top level contexts and then numerous sub-levels. The outcome/energy specific contexts remind me that work-related projects start with planning (putting ideas together), planting (sowing ideas), or fishing (looking for ideas); typically require some harvesting (collecting information) and/or cooking (creating outputs); and end with either eating or tidying-up (consuming the results or cleaning up after them). Otherwise I explore (look for fun things to do) or play (do fun things) -- those tasks are for my free time. I set personnel specific contexts to pull up in a Waiting For context view. My Someday context holds future ideas. I've found that tool specific contexts (computer, phone, email, ....) are generally not useful for me. As someone or many folks here have said ... I have the phone, computer, ... tool with me almost always anyway.

There is likely no one "right-way" to set up contexts for efficient use, though I imagine there can be many wrong ways. Your's seem reasonable enough.

Hope this helps.
