Tried something like that. Was unable to do anything productive after 5 hours without a real deadline.
Could you hire a cheap online personal assistant that would give you the deadlines? Like, you would make a plans for the whole week in advance, give those plans to the assistant, and then during the week the assistant would role-play being your manager. (Using another person as proxy for your planning self.)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.

2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
