You procrastinated anyway. Now get over it.
It was either this lovely Maugham quote or a practical quote, one of disputed origin by either Carl Sandburg or Antoine de Saint-Exupéry. Maugham won out because, well, just read it. Wow. It's so applicable to all areas of life, not only time management, but also so very perfect for reminding us to seize the moment.
Working alone in a home office, it's easy to get bogged down thinking about the past. Perhaps yesterday there was a client problem. Maybe for the past month business has been slow. There are probably nagging thoughts about past experiences in your home office that influence how you still work even today.
This quote reminds us that the past is gone and the present is everlasting. Every moment is a clean slate, a new opportunity.
