I have tried doing "what have I done today and what shall I do tomorrow" in that order, right before I go to sleep. It works amazing whenever I do it. I just need to do it everyday.

What do you think about adding "good" to those questions? Was that a linguistical/cultural thing back then to mean 'meaningful' in reference to himself, or did it mean 'good' as in The Public Good?

Given, we are talking about Ben Franklin, I would be more inclined towards The Public Good rather than "meaningful" in reference to himself. And that is the reason I avoid good in my questions because my questions relate to "meaningful" to myself. :)
