Major contexts are Categories with names in parentheses: (Work), (Personal), (Family). This makes them stand out at the top of your master context list, so you are reminded to always assign them to your tasks when processing. Use short, simple names.
When it’s time to handle family responsibilities, just look at the (Family) category list.
Trog’s autocomplete feature makes these easy to type in. When you set up your strategic calendar Trog will automatically help you budget your time in these areas.
