My goal is fluency, why is that bad?

My goal is fluency, why is that bad? I am 20 and have started with a new speech therapist over the course of the last year and throughout sessions I get reminded continuously fluency should not be the goal and things similar to that. I don’t understand this. I want to be fluent and become a more effective communicator?? I feel like I am stuttering more recently and I want to take matters into my own hands outside of the clinic. People who have stuttered and maybe are not completely fluent but at a point where you communicate mostly undetectable and your stutter no longer weighs your conscience, what did you do? I really want to stutter less and be more fluent for many reasons and want some advice here
