In one month you pretty much have to do the first thing that comes to mind when the month is over.
If you take six months (or better yet a year), you have time to fall in love with an idea, go through the honeymoon stage of prototyping it over a week or two, then discovering you're not into it enough to make it a business. Repeat that cycle a few times, and eventually you'll find something with enough emotional staying power that you can't help but make it your life's work (at least until your next exit).
There's nothing saying this can't happen in a month. But if your attitude is that you're just auditioning ideas during your long time off, you're more likely to make your decision because of fit, not because of time.
By the way, if you have a significant other who doesn't appreciate seeing you idle, this approach is nice because it's indistinguishable from immediately getting back to work.
