I have been reading Kent Becks revised version of XP explained and he's replaced the 40 hour week practice with energised work.

In a high performance environment its vital that you can rely on your team mates. To know that they can be realized upon and that they will contribute to the optimism of the team. Energy sappers drag the team down with negative comments and actions.

teams need to deal with the SAPPERS
individuals need to be mindful of the comments and actions and how they influence the team
energize work don't SAP it!
