Jeff if you're reading, how about a new leadership principle?<p>Work Hard; Live Hard<p>Description: Have a good work life balance. When you're able and its appropriate, work hard. If you're not able, for whatever reason, or if it isn't appropriate to be working, please don't be working.<p>What is deemed able: If you're sick, you're not able. If you're tired, you're not able. If you're grieving, you are not able. etc.<p>What is deemed appropriate: Work <strike>50</strike> 40 hour weeks <i>on average</i>. While working regular hours, work hard. There may also be weeks you need to deliver, there may be weeks you need to be oncall: please work hard (i.e. more). However, if you constantly "have to deliver" or are consistently fighting fires, then something is wrong. This shouldn't be happening. Consider: are you setting bad dates for yourself? is your manager/team setting bad dates for you? Either way, fix that tomorrow. Meanwhile, quote this leadership principle and go home.<p>Scared your manager wont like your new attitude shift? Just quote "Its in Amazon's blood, Work Hard; Live Hard, I have a Kelly Clarkson concert to go to!"<p>P.S. Please realize I haven't given this much thought, every idea requires refinement, and this post is 40% in jest. Meanwhile, if you'd like to help Amazon potentially find a new leadership principle on the internet, constructive criticism or humor are my favorite types of responses ;).
