If you are a typical full-time, working American, you probably spend nearly 70% of your day sleeping or working. The average American (ages 25-54 with children) spends 8.7 hours working each weekday. This doesn't include any commute time either.
When more than 2/3 of your day is spent working or sleeping, you really should do what you love. Is it time to start rethinking your career?
