Choose your preferred context view method and make sure it is easy to access, with a single click, without defining search terms each time. If you need to define and save custom views, do that now and name them appropriately.
Consider setting up a master contexts list.
Make sure your context views work for all active tasks regardless of other ways you may classify your tasks. For example, if you use folders for contexts and you create (Work) and (Personal) folders, but this prevents you from seeing (Work) and (Personal) tasks in your Errands view, then you cannot use the folders feature.
