Reading Aloud, much and often or even little and often, is important in helping us gain more clarity into what it is we're actually reading. At the same time, it gives us practice in verbalization and vocalization which, over time, enables us to speak and present better and also helps us in writing more effectively. Communication skills are enhanced and this is foundational to our flourishing and adds value to our contribution to others around us in our own lives.

Over the years, people have often asked me for some time so that they could "Pick my brains", which is almost verbatim. Want to explore ideas, discuss possible options for whatever project you're involved in or "Have a bee in your bonnet", as they used to say in days of yore? Come Ask Grampa, perhaps with two of your friends or colleagues. Two hours, max. You will see progress or at least change course or trash the project and explore something else. But you'll get somewhere.
