Piera, excellent suggestions to reduce stress and overwhelm in our daily work.  Because many people will read your post, agree it's a "good idea" and keep multitasking anyhow, I challenge others to post their response to " and what will you do today to remember to practice focusing?" or implement just one of the suggestions.

A visual cue, post-it on your computer screen, or quiet notification as a reminder to get into the habit of the new behavior may dramatically increase the odds your suggestions are put to use and are not just "a good idea I was going to do someday!"
