Thank you for these interesting three questions. They will require three different answers.

1) Ability to make friends – I had a small group of friends when in public school, some from my childhood neighborhood, and some who I met in my classrooms. It was increasingly difficult for me to speak through most of my public school years, so it became increasingly difficult to meet new friends. But I enjoyed the friends who I had.
When I reached college – and I attended in my home city – most of my public school friends were gone, having moved to different cities. So I was essentially friendless for a while. For about a year and a half, I was reluctant to make new friends, due to my then very severe stuttering.
A speech pathologist who I was seeing at the time (he stuttered himself) reluctantly got me to admit that I had no close friends to speak of. (I was then about age 20.) He told me that I MUST make a major effort to meet new people and make friends – REGARDLESS of how severe my stuttering happened to be. This was a most difficult assignment for me, but I did my best to comply. On the campus where I was then a student, I made a major effort to meet and talk with as many of my fellow students as I could.
I then discovered some points that amazed me: Most of these students were very interested in what I had to say, and were patient with me as I spoke. They did not care that I had severe stuttering. I also discovered that the more I cared about other students, the more they cared about me. Before long, I was making MANY friends on campus.
Since that time, I have not had any problems in making friends. It’s been now over 45 years since that social breakthrough, and I have enjoyed being with many friends over these many decades.

2) Dating – I was rather slow in starting to date, compared to others of my age, due to shyness brought on by increasingly severe stuttering. I was about 17 when I had my first dates, and the first girl I dated was someone who I had known since the first grade. Her family had known of me beforehand – as I had a reputation of high intelligence and musical talent. My severe stuttering was a non-factor.
In college, one of the results of my increase in socializing (see my answer to #1) was a girlfriend. My stuttering was quite severe, but I was making a major effort to meet as many students as I possibly could. Later, she told me that she was amazed that I was so talkative, even though it was obviously difficult for me to speak.
I spent about 12 years in graduate studies in various fields. During those years, I dated a number of women who were also graduate students on the campuses where I was studying. They all knew I had a severe stuttering disorder before dating me, so that wasn’t an issue.
When not in graduate studies, I used personal ads to find women to date. Typically I advertised myself in singles magazines and in dating ad sections of newspapers (this was long before online social media), and met many women that way. I received written responses first. Before calling these women, I practiced fluency techniques I had learned in therapy to maximize my fluency in the first phone call. Then during this phone call, I would tell the woman of my stuttering disorder. Some of the women who I met through the personal ads became my girlfriends who I dated for years.
When I was 45 years old, I was still a bachelor. At one of the early stuttering-related websites (21 years ago), I met a fluent woman who had always had a mysterious interest in stuttering, and who was drawn towards people who stutter. I was then living in Massachusetts, and she in Norway.
We corresponded by E-mail daily for three months. Then she flew to the U.S. to meet me in person. We were engaged one week later. Four months after that, I moved to Norway, and we married 10 days after I arrived. We have now been happily married for 21 years.

3) Getting a job – This has been the most problematic for me of all these three areas. When I lived in the U.S., I had various kinds of part-time work – as a pianist in nightclubs, restaurants, and at concerts (these jobs were difficult to get, as I usually had to call managers to schedule auditions); concert director (the employers knew beforehand that I stuttered, and it was a non-issue); musio instructor, for one graduate music course and a small number of private students (I got these positions due to reputation, and my stuttering was overlooked); computer programmer, where there was little requirement to speak; and as special needs tutor (by that time I had a speech pathology background).
But none of this work was full time. Getting a full-time professional position eluded me, despite my many years of graduate education. I suspect this was due to severe stuttering during job interviews.
I have degrees in music, mathematics, and speech-language pathology. I applied for a number of teaching positions, and was regularly turned down. I completed my graduate clinical work in speech pathology, but was unable to find the required Clinical Fellowship Year position.
After I moved to Norway (see my answer to #2), I found work as a foster “weekend parent” for a girl with special needs. My wife was there during the interview process, and greatly helped me in obtaining this position. I have now been engaged in this work for 20 years. In addition I sometimes appear at community events as a pianist/composer.
