You lie in bed in the morning, reluctant to swing your legs out from under the warm embrace of your blanket. After several bleary minutes, you finally rouse yourself, throw on some clothes and head to the office. Having arrived at your desk, you stare blankly as e-mail loads on your screen. When you first started this job, you derived deep satisfaction from addressing the day's challenges efficiently and artfully. Yet the optimism that used to buoy you is long gone. Now your morning coffee gives you the only jolt of energy you'll feel all day.
