A good delivery does justice to the points you've gathered and to the speech you've worked hard to shape. It comes with practice and a lot of planning and from trusting and relying on your individual style. Don't try to adopt someone else's style; your audience will sense something is amiss, and you won't feel comfortable. If you be yourself and be enthusiastic, you will be well on your way to a stylish delivery, ready to use your delivery skills on a daily basis, starting with meetings.
