For a while, the endless guru-talk about why everyone should keep little Barnes and Noble-style notebooks in their back pocket with a worn-out pen and thoughtful look to the worn pages really turned me off. I avoided notebooks because I thought they were a fad.
After 3-years of keeping notebooks with me at almost all times, I cannot say that anything masterful or genius-like has taken place inside the pages I've filled. But I can tell you that my life has improved as a product of those pages. I don't know what the benefit would turn out to be for you, all I can say with confidence is that there will be a benefit if you make keeping a notebook a habit.
