I already have blog posts that advocate using a computer for many communication tasks instead of a phone or smartphone. A computer is a much more powerful device and can accomplish more, and more different tasks faster and easier than a smartphone. If you visit sites.google.com, you will find tools and forms for creating a web site. Included are viewers to see what your site looks like on a computer, on a smartphone and on a tablet, like an iPad.
One way to more or less keep your computing time under control is to make mental or paper notes about things and people you want to contact and then setting a time to actually use a computer to get that done.

On a 2nd subject, you probably know that breathing is important to stay alive. When a human stops breathing, they are either dead or close to it. However, there are other valuable angles to the subject of breathing. The book by James Nestor, "Breath", has recently been popular but I favor the books by Larry Rosenberg, "Breath by Breath", and by Gay Hendricks, "Conscious Breathing".
Breath by Breath takes a relaxed but wide view of the use of awareness of breathing and focusing one's attention on one's own breathing. Highlights from my reading of the book are here:

Here is a list of my blog posts related to Rosenberg's book:

Old eyes like mine can be irritated by focusing on one anchor. I was pleased to find that careful inhalation and slow controlled exhalation can be an excellent anchor for my attention and during the whole time, I can keep my eyes closed.
I have gotten plenty of good ideas and encouragement from Dr. Gay Hendricks. Highlights I noted from his book "Conscious Breathing" are

I enjoyed his confession that he used to be something of a pain in his enthusiasm for "breathwork". I was surprised at the idea that pulmonary and other physicians have suspected that many health problems come from poor breathing. I think Dr. Hendricks put his finger on one source of difficulties: the abdomen. Several sources emphasize that good breathing involves using the diaphragm and that it is far more basic than expanding the chest. Yet, Hendricks points out that expanding the belly to use the diaphragm fully contradicts the fashion objection to a protruding, rounded belly.
