I call it "repurposing"

Do it Tomorrow and GTD: Comments on the two systems? - The David Allen Company:

"Hi, I've read all of Mark Forster's books now and I have to say that I've found them extremely helpful. My problem is with procrastination and overwhelm, and Mark's book Get Everything Done was a revelation.

I just read it last weekend and I'm still thinking about it, but I'm beginning to think that for me it was even more helpful than GTD. It really gives you a lot of insight and practical tools to deal with resistance, and helps you get started when you feel stuck.

The problem I see with GTD is that it's not possible to think through all your work in advance. Life moves too fast. I've been working with GTD for a couple of years now and I've never been able to "think about once a week." In my profession, working is thinking. The idea that I could do a weekly review and come up with everything I needed to do that week is just not possible.

Get Everything Done doesn't delve into that issue specifically, but it does give you tools for getting going. My problem is that I get overwhelmed because I don't know where to start. Forster has helped me to understand that I need to just dive in, and that giving myself time to think is not goofing off. "
