HOLLYWOOD, Calif. — Revenue from 3-D movies is likely to set a record this month, according to the International 3-D Society, which said 3-D ticket sales could propel the summer box office take — for all movies — to an all-time high.

Four major 3-D movies are out this month — “The Great Gatsby,” “Iron Man 3,” “Star Trek: Into Darkness” and “Epic” — and 18 more are slated for release this summer.

Who is more important: you or a group of your fellow nonprofit volunteers or professionals? What signal are you sending when you direct your attention to your mobile device instead of the group’s discussion? If you believe the work of the organization or institution is unimportant, say so and work with your peers to restructure meetings. If not, give your attention to the business at hand. Each of you has carved out time from your busy schedules to attend the meeting. Make the most of it.
