Fantastic essay by Scott Berkun:

People who are always busy are time poor. They have a time shortage. They have time debt. They are either trying to do too much, or they aren’t doing what they’re doing very well.

On the other hand, people who truly have control over time have some in their pocket to give to someone in need. They have a sense of priorities that drives their use of time and can shift away from the specific ordinary work that’s easy to justify, in favor of the more ethereal, deeper things that are harder to justify.
