A quote about education (attributed to George Pólya, although I can't find the source): "It is better to solve one problem five different ways, than to solve five different problems one way". I would guess that similarly, if one wants to educate oneself about world affairs, one should (regularly) take a few of the most important (current) issues/events and learn about them as in-depth and from as many angles as one can, synthesizing everything into a big picture, rather than pay attention to every non-issue. Of course, in order to be able to do that, one should try to learn history, economics, statistics, game theory, public choice theory, geography, biology, etc (curiously, in some cases reading something about the past might be more beneficial to understanding the present than reading something about the present itself). Of course, in some situations this "issue/event centered" (vs "news as they appear") approach could also have some drawbacks, for example, if, for some reason (e.g. (non-)availability of relevant literature, ideological reasons, etc.), one approaches events only from one or two angles ("hedgehog", as opposed to "fox") one could easily fall prey to confirmation bias.
