Ok we'll it's actually something I learn from a book called ZTD. But simply put, every evening I will empty my inbox and then scan my next list picking the tasks I want to complete the next day. I have a morning routine that I follow first thing AM (which becomes habit after a while) then move onto my planned tasks. If I don't complete them all (which does happen, life being life n'all) I usually do them asap the next day.

I find by adding a little structure via planning to GTD makes a lot more sense to me personally. It gives me a sense of control and I can get more done with a little rigidness rather than 100% in the moment decision making ala GTD.
