Ah yes, I remember it well!
Being transsexual in the 1950s and 60s was an extreme struggle! Doctors didn't know squat so there was so much I needed to learn, biology, the endocrine system, negotiating skills, psychology - basically all the things to help me get where I wanted to go and to not be derailed along the way. I also had to learn patience and dogged determination. The struggle went on for more than 10 years and became a matter of life or death in the last few years.
When I finally won out and achieved SRS/transition it was just an incredible sense of relief. It was just euphoria to not have to struggle any more and I spend a year or more just revelling in the ease and comfort of my new life. I didn't want to do anything other than enjoy life.
Later, in my career, I turned the determination and stubbornness I had developed toward my work and did extremely well in my career.
Now, being retired, I am having a great deal of trouble "letting go" of that drive. I am getting better but I still have to learn to sit back and relax.
