One of the toughest, and most important jobs of a lawyer is to tell clients the bad news, that what they want will not be easy to get, and may be impossible. Having this information allows clients to adjust their strategy to get what is realistic, instead of wasting time and money chasing the impossible, instead of getting some of what they want, getting nothing.
It is always easier to tell people what they want to hear, that they can have it all, but a good lawyer does not always do that.
