Does educating others about stuttering come at a cost?

Does educating others about stuttering come at a cost? Recently I've found less motivation to talk to other people about my stuttering. As a background, I frequently self-disclose to others that I stutter. I've done this for years and I think this is helpful for me. It removes the elephant in the room and makes them and me more comfortable. It also indirectly helps my speech to be easier. But, recently I've been catching myself thinking, "Is it worth the effort to self-disclose to this person or educate them about stuttering?" This happens more when it's someone I know I won't see again, so the payoff for me is less. Is it selfish? I question it because if I push through it maybe I can help the next person who stutters that this person meets?
