You have made a list of the right priorities.
Now the game begins.
Distractions swoop down to shatter your focus. Emails, phone calls, knocks on the door, and new items at meetings. Since many of them have merit you will be tempted to drop your list and follow them down a side path to a destination about which little may be known. Call it Not One of Your Priorities.
Sometimes the side trips are unavoidable. Work, like life, can be messy. But the list should not be forgotten. Keep it nearby.
