I am having trouble integrating habits into my GTD system. By this, I mean projects to develop daily habits - such as getting daily exercise, or meditating each day for 15 minutes, or setting 30 minutes aside to read.
I find I have a lot of actions in my GTD system, and seem to forget habits I am trying to develop. The actions for the habits are straightforward and essentially the same every day. I could enter the next action every single day... but that seems like a waste of time.
What do other people do for habits they're trying to develop? Where does this fit into GTD?
