Being over-scheduled and over-committed is a part of the culture of entrepreneurship.
However, being perpetually busy is akin to being sloppy with your time and is ultimately a form of laziness, says Tim Ferriss, entrepreneur and author of the best-selling productivity book "The 4-Hour Workweek: Escape 9-5, Live Anywhere, and Join the New Rich."
"The default mode of Type-A entrepreneurs is to do more — whatever it happens to be, do more," Ferriss tells CNBC. "If I have a problem, do more. If I am feeling stressed out, do more."
And while it might seem logical to increase output, "indiscriminate activity is a form of laziness," he says.
