《妈妈的土豆沙拉(英文版)》由Regina M. Stockus著：according to the challenge,opportunity and focus of this treatise, I hope to clarify and shed some light on the following issues :
· To identify what sets each of us apart, which will spur us to do greater things.
· To discover what makes us happy and then motivates us to do something well.
· When do we reach this nirvana?
· When do we know we have done the best that we can?
· Who decides?
· How do we measure true efforts?
· How to continue this ideal level of effort?
· How to balance ERR with PPR to achieve this ideal state of optimum DE?
· And the greatest challenge of all, how to train trainers and managers and supervisors to implement these theories into practice?
· The greatest challenge, especially in the service sector, is achieving DE on a sustainable basis when we as Humans cannot?
· And lastly,what is then the ideal?
