Your are right. Limiting yourself to a career you only pursue to avoid stuttering is unfulfilling. Everyone has his own threshold of comfort as a stutterer. If a person is ok with communicating though he stutters, the reward of engaging in his preferred career is greater than the downside of constant stress involved with stuttering. It’s always a personal choice. Many stutterers feel so defeated by their inability to communicate they choose to limit their communication to as little as possible. I know my stuttering was an embarrassment but not so much a detriment to communication.
