If working in construction, or another manual labor job, was a driving element for crossdressing, does that mean that there was little interest in crossdressing before you worked in that profession?

Personally I can't remember a time when I wasn't attracted to crossdressing. There are so many factors that can contribute to my crossdressing. I'll list just a few:
1. My mother made it clear that she wanted a girl when I was born.
2. My sister was born a year after me, and she was pampered by my mother. I was jealous, and believed my mother would love me more if I was a girl.
3. My older brother beat me up routinely, even breaking several bones. I believed that being a girl was a way of escaping.
4. My next door neighbor was a very feminine boy, and we were good friends. He loved crossdressing too. (I didn't realize it then, but he was gay, and when he got older he died from HIV.)
5. As a child I had a very low self esteem, highly introverted, very shy, and very quiet. (One of my teachers even called me a mouse.)
6. I admired the in female adults in my life, they were nice to me. Male adults were vulgar, heavy drinkers, smokers, who showed no interest in me.
7. In my world view, parents preferred girls. I never doubted that I was a normal boy, however I also believed all boys secretly wanted to be girls.
8. It wasn't until I was in college before I even imagined such a thing as "male privilege". Before that I believed girls had all the privileges.

Yes, I believe I experienced some gender dysphoria in my childhood, but by the time I was an adult I had accepted by biological gender. In the end my brain was just hardwired to respond to crossdressing by releasing a host of feel-good neurotransmitters, and they make me happy. An old saying, "give me a child till seven, and I will show you the man," helps explain why I need to crossdress today.
