It will always be easy to get people who talk pleasantly, oh, king, but it is impossible to get them who talk judgmentally and give suggestions. These suggestions may not be pleasing but will gradually solve the problem. And it is impossible to get listeners to such advises.
(Source: Ramayana - Chapter 3, Aranya Kanda, sarga 37, verse 2)
(Here Mareecha advise Ravana against abducting Sita)
