Honey (don't take offense, I'm southern), do what you want to do! Go for it
You sound like me. My favorite job was with a seating company here in TN. I was so grateful when they took me straight to the area the men were working in, lol! I was very prepared to tell them "No", in no uncertain terms, had they of tried sticking me in the section where the women were sewing.
I was the only woman in that side of the building with the men. I ran very large saws, sanded, grinding, and worked with the bending machines and spot welding with the machines. You see, I worked with steel pipes
And I LOVED it! I enjoy working with machines. I also grew up with boys as I am the oldest out of 5. I raised two of my brothers. I hated all the girly stuff honestly.
My point being, we all have to pursue our dreams. I know I don't have much strength myself, but my determination and will to do my job is important. So, we are very much alike in our joys of working in a male dominated field
Retail...I wouldn't be happy doing that either
Good luck and blessings be with you every step of the way.
