NLP, phrasing and pressupositions

In NLP we learn about the the use of pressupositions and their effects, but I can't help but marvel at whether sometimes their usage and other linguistic combinations are not as "considered" as they might be...

Let's look at a few examples

Effortless Success - Effort = "less success?"

"Get the life you want" - presupposition that you don't already have it?

"Welcome to X NLP Academy, the UK's leading academy?" - "leading" according to whom exactly?

"At NLP Life, you will learn to release the amazing person inside of you" - assumption that "the amazing person (amazing defined by whom?") is not already "released!
