Yes & No. I have a "high level" mindmap of all goals, work and personal. Then within each individual goal there is a process map and accompanying "to-do" tasks with them. In this way at the individal level of the to-do list there is separation. That said, however they are all kept within the same "master goals" binder.
I keep them together and linked to my diary. One diary and one to-do list avoids confusion and one spilling into the other. Sometimes you can check out a personal task along with a work task.
