There's no right amount of productivity for, say, in, like, a specific number that you have to hit each day. Unless you work in a center that's, you know, you've got sales goals or outbound volume or number of patients you have to see, or a lot of accountants and lawyers. We all have billable hours. That's natural. But I think it's a real dangerous way to think about your life. Because at the end of the day, the question I would go back to is, are you getting the results you want? Any number of things you can be dealing with your own personal health issues that affect your capabilities. I think it'd be really, really dangerous for you to get too wrapped into how productive you're being.
