Choose a quote from an individual recognized by the audience
Using quotations is also a way to overcome some of your fears of public speaking, shyness, anxiety, etc. and to bolster your confidence up there in front of your audience. Since quotations are the words of others, and more pointedly the already-consensually-approved words of already-consensually-respected-and-admired individuals, using quotations is a way of invoking the support of those great minds up there with you in the spotlight. Rather than judging you on your choice of words, when you use a quotation the audience judges you instead on your choice of quotation. So as long as you choose wisely, you can relax into the fact that you come to the podium armed with some of the tried and true wisdom of the ages.
In using quotations in your speeches keep the following considerations in mind when looking at how to close a speech: Choose a quote from an individual recognized by the audience as having the right to comment with authority on the subject matter of your speech and the field of interest of your audience, and choose an appropriate and relevant quote. Don’t try to stretch a quote to fit your speech. Find a quote that fits in naturally.
