I retired about a year ago. I spent 30 years in a field that is nearly all male. I did a lot of proving myself the first 10 years or so, but ultimately became one of the most respected people in my field over a 3 state area. Overall it was a great experience. When the micromangment of the more recent management teams changed the work environment dramatically, I retired. You enjoy it and/or do it well, you go for it!
