Perpetual devotion to what a man calls his business, is only to be sustained by perpetual neglect of many other things.
— Robert Louis Stevenson
Love this quote that Shawn Blanc highlighted as part of his Focus Course and he follows it up nicely with his own take on it:
May devotion to our business not be sustained by neglect of our health, relationships, values, and even our own happiness.
— Family Balance by Shawn Blanc
Both worthy additions to DailyMuse.
