Have you ever squandered an hour? How about an entire afternoon?
The result is often one of regret or even remorse. Those gifted minutes, just slipped through your fingers and will never return. What to do?
The answer of course is simple- start anew. Mother Theresa of Calcutta once said, "Yesterday is gone. Tomorrow has not yet come. Let us begin." I have that quote in my office and it means a whole lot to me. Get on your horse man!
BNET has this interesting post about office politics. They can be fierce because they are "out there" and you're "in there" trying to do your job. You could run from it but that would be lame. You could embrace it but that would be stupid. Final choice- build resolve by doing the little things exceptionally well.
Don't wait for the "right time" to get back on your horse after a set back. Getting Things Done is about renewing your efforts at street level, in the nit and grit of daily work. Why wait another minute?
