i am having a hard time trying to start up the essay. how would i start up the essay?
You can't determine how to start the essay until you've decided what you're going to say in the body of the essay. Decide which aspects of your professional experience you are going to write about and to which elements of the book you are going to link them. Sketch out a rough outline of that. From there, you may get your own ideas about how to introduce the essay, or you can post the outline and we can help you.
