The focus of a eulogy should be on you and your life. A religious leader might speak about your religious faith, a business colleague might speak about your professional life, and a family member might speak about your personal life. Many people share memories or tell stories in a eulogy, to help illustrate the nature and character of the person they’re speaking about.
Sometimes the topic of the eulogy is left up to the speaker to decide, while other times the topic has been chosen for the speaker. Whether speakers will have assigned topics or may speak about whatever they choose is entirely up to you. If you would like to choose topics for the people who will be delivering eulogies, talk to them about that ahead of time. Let them know why you’ve chosen them to focus on a particular topic, and be open to answering any questions or addressing any concerns they might have. This way, when the time comes, the people you’ve chosen to speak will be prepared, and will fully understand your wishes.
