There is no reason to show off. The most successful people with the greatest achievements talk about them like they are very insignificant.
I have heard different guys’ response to a girl’s questions of “What do you do?” go into a very dramatic long, detailed answer where he thinks he is being subtle about how cool he is, or how prestigious his job is, or how smart he is to have gotten there or how wealthy he is because he did.
This looks very insecure and women are masters at seeing through this type of thing.
Usually with a qualifying type question like that, I am [private]flattered that she is interested enough at this point to want to know more but I still give her a teasing/joking (Obviously BS) answer and spin it back to her, have her qualifying herself to me. “Ya, I have finished school for it and now I am working by scraping the gum off the bottom of seats at movie theaters. Very demanding nowadays…What do you do?”
Or I may tell her “I jump out of cakes at birthday parties.” Or “I am a disposable lighter repairman. 4 years of schooling finally paid off. “
Usually the girl laughs or chuckles to my joke, then goes on to tell me seriously about her career paths. Now this has the momentum generated of her qualifying herself to me, working to win my approval.
When I do get to what I do for work, rather than tell her what it is, I explain to her all the reasons I love what I do. I’ll talk about how I got into it, and how it fulfills me very much. “When I was a kid my dad told me to think of something that I would do all day/every day for nothing. Once I could earn a living doing that, I am successful. At this point, I am as close to that as I can imagine, and the direction I am in, what I have planned gets even better.”
Even as she asks me for details I stay very vague at this point. I spend the time talking about the fulfillment it gives me to help people to their successes, or examples of why I love what I do.
