In any talk there are two areas that need particular care.
1. How to start. One does not just want to wade in; you have to give your listeners time to tune in to you and what you want to say. TRY to remember, if all you can do is just tell a story the talk will be over in a flash and no one will be much the wiser. So to begin: tell a story (from a book or one that you know), use an analogy, use a quotation, refer to a song, draw a word picture, demonstrate, paraphrase, create an image in the listeners mind, simplify the story, personify (if I had been the woman etc), devil’s advocate, mirror so ask the audience to be with you in your story. Be careful with humour as it can go very wrong, just let it emerge as you go along.
2. Decide how you want to end. Often in a talk finding a way to wind it up is hard to do so in a way its the first things you need to think about. But do NOT over embellish by adding several points that are not in the essential or find obscure points that no one will understand.
