Now for Epicureans the goal is to live life the most pleasureably, because this life is the only life. And to live pleasureably both includes and goes beyond tranquility.
Yes I think a large part of the issue is that this kind of formulation (and yours here is very on point I think) is necessarily extremely broad and even "abstract." "Living pleasurably" is such a broad description that (necessarily) means so many different things to different people that its necessary to keep in mind that it's an "outline" type of statement that must be translated into reality.
