One of the methods that have been the most effective for me is to over prepare for each speaking event. Become very familiar with the audience and organization and get to know what their purpose is. Lions Clubs support programs for sight; you might mention something about the program or collect used glasses for their program. The Rotary Clubs have many programs in the community and each club typically focuses on a specific project. Find out what their project is so you are well informed. The Kiwanis Clubs focus on boys homes and other local projects.
If you’re speaking at an organization, research them on the Internet and try to get background information so you will be well prepared. You might interview four to six key members of the group and find out what their challenges are. Be sure to provide your audience with specific benefits but always leave them wanting more.
