The lecture is LONG, so listen to it while doing something else! It is geared toward business, but a lot of what he says is applicable to personal life.
If you try the Excel list, I think you'll find yourself really liking it. I have become completely dependent on mine!!
It is so nice to not have to stop and think, okay, did I do a, b, c, d ??? What do I still need to do?
I did the same thing, tweaking it over the course of a couple of days as I remembered things that needed doing. I have notations next to things that have to be done semi-weekly, weekly, bi-weekly, etc, but that may be too rigid for you. Because of all my animals, including several special-needs critters, I have to keep track of who needs what and when.
Wishing you lots of luck, although I don't think you'll need it!! I find that those people who have motivation and ambition don't seem to need luck as much as those who don't!!
