Why should we ever do more than the job we are paid to do? It isn't like any of these companies care about us at all. And it has been proven that working more hours doesn;t increase your productivity. Humans evolved to work about 3-5 hours a day. The eight hour work day is a very recent industrial creation. Created mostly by greedy rich assholes that would have worked children to death if the socialists and unionists hadn't have risked their lives to force laws to be passsed.

I think neurology and science are far better guides than these postive thinking "gurus" will ever be.
