Books on business tend to be theoretical, fluffy, and oftentimes not very practical. The HBR: New Manager book has a few fluffy chapters I skipped and skimmed over. I think "Saving Rookie Managers from Themselves" and "Management Time: Who's Got the Monkey" are excellent reads. The former has a few pointers on projecting confidence (something I KNOW I need to work on); the latter is the magnum opus of this collection - the monkey. The monkey is a synonym for tasks you assign to your subordinates. Through elusive, subtle measures subordinates (I think due to human nature) try to shift the responsibility from them to you (as you are the superior, clearly more intelligent manager whom can handle all). I think the advice in this chapter is particularly tangible and practical. 5 stars for those chapters.
