Do it 

Everything  about  the presentation is  ready and so  are you. The only  things  left if to face the audience in a confident and positive  manner and leave a mark on them  when you are in the  process of  finally presenting the matter to the audience you  need to  be extremely careful about  the introduction and the conclusion of the  presentation. When you commence keep  one things in mind capture the attention of the audience right at the start by making the opening  spell binding. If  you do  not capture  the attention of your  audience right  at the start  you have  lost them forever. Any amount  of persuasion  or the  use  of stylistic devices at a later stage will  not help   you to  regain  their  confidence in your  abilities for presentation.
