Indeed, as the article describes, it's not so much the stress of freelancing as the particular stress of billing by the hour. While I/my shop nominally have billable hour rates, some time ago it evolved into projects that are estimated as the rate of billable hours plus materials, but billed on a per-project basis. The project is due for the agreed amount, whether I spend the planned number of hours, twice that, or half that. This is decidedly less stressful for both me and the client. I still have the stress of meeting the schedule deadlines, but I no longer feel that stress described in the article of 'wasting' minutes I'm not productive. If I take a break, it may feel that the schedule is slipping, but it doesn't feel like losing an irreplaceable opportunity cost to earn $x in that 0.2 hours.
