Usually this kind of self-serving "honesty" will sabotage your success. If you can't say something nice, don't say anything at all. Realize that sometimes your own words can, and probably will, come back to be used against you.
In "The Art of Connection," Susan C. Young emphasizes the dangers of self-serving honesty, suggesting that it often undermines one's success. She points out that expressing unfiltered negative opinions can lead to unintended consequences, impacting relationships and opportunities negatively.
Young advocates for a more thoughtful approach to communication, urging individuals to refrain from speaking if their words cannot contribute positively. She warns that careless remarks can be used against you, reinforcing the importance of choosing one's words wisely and fostering a constructive dialogue.
