Coming up with good ideas is hard enough, but convincing others to do something with them is much harder. By definition, the application of an idea means that something different will take place in the universe. Even if your idea is undeniably and wonderfully brilliant, it will force someone, somewhere to change how they do something. What is your scope? What is the structure of your pitch? Will you use images in your presentation to support your pitch? Who is your audience? What is the story-line? What is the tone of voice? How will you behave on stage? How do you get prepared and how will you rehearse?
Many things to take into account, I can help you with this as I do not focus on one aspect but I can embrace the whole picture.
