What Size Load Should You Bear?

If i stress you involuntarily, you tend to react with defensiveness and fear. But if you take the same challenge on voluntarily, your psycho physiological response is completely different. So it's different to hoist a load voluntarily than it is to have it thrust upon you. And so the question then might be, what sized load should you bear? And i think the answer to that is the biggest one you can possibly carry. That will insure that you know that you have something meaningful to do.
