Wow, that is such a nice compliment your CEO gave you Hope. Hmmm, setting up the right proposal could bear some fruit for you. However, if you see your boss as an obstacle that isn't going to fit into what you have in mind you need to state that and why. If YOU are looking to replace him, then you will have to explain why that is necessary and how you can do a better job. You have to be certain you want this.
