It should be something that doesn't take much physical stamina. Don't got that.
It should be something that involves reading. I do a lot of that.
It should be something that would presumably effect a change upon me.
*make every recipe in one cookbook. I think it would be fun for me but not for others.
*follow some kind of get-rich-quick plan. No...
*Read all the works by one specific author. Again, boring for others.
*Try to make 1000 things out of tofu. Well, it could be ...not a book...
*Resurrect my sims and make a sim of A.J. Jacobs and make him...I'd love to, but my sims are on my dying computer. I'll never get them back, I fear, and I do miss them greatly.
*Make scrapbooks for every conceivable occasion that happens in my family. Oh lordy. Would make good fodder for family talk but not a good book.
I'm just fresh out. I'm going to finish my beer and seek inspiration elsewhere.
