Ask Questions to Win Cooperation
This is a positive book. We are interested in what people should do to be better leaders of others—and of themselves. The wrong things we shall mention seldom. It’s better to keep our minds on the best ways. From time to time, however, it is wise to give passing mention to possible pitfalls. In asking questions, for instance:
Don’t pry into personal affairs.
Don’t ask questions unless you are pretty certain the person addressed can answer them.
Don’t ask questions that seem to cross-exam.
Don’t ask questions to show off yourself—ask those that help the other fellow show off.
