When we keep a journal we automatically keep bookmarks for ourselves
Programmers complain about distractions all the time. But when we journal and document our actions, we can drop them in the moment and pick them up later from where we left off. It’s like bookmarks for our lives (see next actions 2.7).
We will also have a history of our actions in the journal, which can be used as a reference when we have to go back in time.
