I don't think the quote calls anyone lazy. All he's doing is pointing out the contradiction between saying "I would do X but I don't have the time", and engaging in time-filling activities. It's fine if your other responsibilities (family, etc) don't leave you able to take on something else. Nobody is criticizing you for putting your family ahead of your startup - you'd be insane not to. But the first step in overcoming an obstacle is honestly identifying what that obstacle is.
