It doesn't seem to get mentioned very often on DV. There's no tutorial about it. LD beginners mention doing countless RCs throughout the day but rarely mention prospective memory. Why is this?

I love training my prospective memory. It comes in useful in real life, and for LDing I've got to the stage where I will automatically ask, "Am I dreaming?" when I see some (not all) of my DSs. It gives me something to think about during the day and keeps me mindful. Even though I'm not sleeping I can know my daytime efforts are contributing to my chances of LDing.
