Having just read this well written and researched book, I have decided I do not want to live in the shallows.  You will have to read the book to find out what this means, but it is important!

What this means for me, in terms of action, is that I am going to only look at Facebook on weekends, and only spend one hour max in the evenings (but not all evenings) answering emails, surfing, internet shopping, or whatever.  

Valuable though some of this might be at times, it is important to cultivate the discernment of what is good, better, and best.  If the good crowds out the best, that's not good!  And for me, the best includes what is most threatened by too much time on the internet and the like.  What is most threatened, according to this book, and I think it is correct, is the ability to concentrate for long periods of time on one thing; to think deeply; to read good books and make them one's own in one's long term memory  (ditto for good music, etc, etc.) to go out in nature (minus any electronic devices!) and truly commune with the Divine Creation in which we live;  and of course, take ample time for creativity, or old fashioned crafts like cooking, knitting, writing letters by long-hand to beloved people.   How much of this gets crowded out by our immersion in the communication gadgetry that so fills our lives!   So the question for me is:  not either-or, but what is the BEST BALANCE in my life between using the media available to me, and other things which are at least equally if not more important for my soul, spirit, and body.   How will you find that balance in your life?  And do you really realize what is at stake?
