The problem I experienced with "measuring 'look into'" is that you're not in a position to do so at that moment. "Google 'mend chair leg'" may be a proper task, but it does not capture what to do with it. "Write down best 3 posts" is not something you should commit yourself to before Googling; it's the vague act of "looking into" that generates such actions. You can't tell in advance if you'll need to read blogposts, watch videos, browse a subreddit, etc.
In the end I created my own terms like RESEARCH and BRAINSTORM with well-defined actions attached. RESEARCH means "spend a block of time BFSing on Google until you feel satisfied", while BRAINSTORM means "spend time in front of a whiteboard/piece of paper and dump your problem until you're able to identify specific courses of actions, which then will become your actionable items".
But in the end, I still feel that some problems are not well-suited for GTD - mostly those requiring to improvise as you go along.
Ah, absolutely. I think what's important is recognizing when a task is vague (intentionally or otherwise). It could be "Google 'mend chair leg' for 25 mins and list out next actions', and then those actions become new tasks. I think we're definitely in agreement here.
If there's a misfit between a problem and GTD, the challenge is to figure out how to frame the problem properly.
To zoom out a little- GTD won't create an inspiring work of art, but GTD will manage the artist's schedule, and free her up to read more, meet other artists more, get inspired more, etc.
