At DennisKennedy.blog, a post by Dennis Kennedy titled "Great Advice on Public Speaking" suggests that a speaker's performance improves in proportion to how passionate he or she is about the topic.
It's definitely true. A little passion goes a long way towards ensuring an audience will listen to a message. Throw in some enthusiasm and they may even embrace it.
That these principles apply to a lawyer's performance at trial or motion hearings is obvious. How can you expect a judge or jury to believe in your cause unless you believe in it first?
Admittedly, not every lawyer has the luxury of working exclusively on causes in which they believe. If you happen to lack enthusiasm for your cause, what can you do about it? First, try to make sure it's not too obvious. Second, think about how it affects the settlement equation. Your own lack of enthusiasm often says a great deal about the merits of a case.
