Hmmm, that's an interesting question.
I do need to implement this "Not give a damn" in more areas of my life. I have applied it in two areas of my life rather successfully I think, so after reading your post I thought about how I could apply it to more areas.
The two related areas I applied it came in term of giving speeches in Toastmasters and in leadership. To overcome my nervousness in toastmasters, I decided I would stop caring about the audience - I would stop caring their reaction, that the audience was there to support me, not the other way around. That their role was to help me, it wasn't my role to do anything for them. So with that out of the way, I started focusing on giving the best speech for the the speeche's sake - as if the speech was an idea and a physical object at the same time. I would shape my speech to be the best object it could be and I felt much more relaxed and enthuastic during my speeches.
I also used a lot of visualization to reinforce this image, this idea that I was giving a great speech without caring about my audience's reaction - in fact I stopped visualizing their reaction at all. I simply started visualizing how I felt (in command, confident, cheerful, etc, whatever I wanted to focus on) as I delivered my speech, and my speech would simply flow effortlessly out of me.
The result is that I started giving speeches that were much better then before, and my audience, despite the fact I officially didn't care about them, started enjoying my speeches much more. Since I wasn't concerned about their reaction, I was freed from worrying about it, and I could tailor my speech much much better to their reactions - if that make sense. That is, while giving my speech, if I saw someone objected or confused about something, I could quickly explain it more without worrying about their reaction. So in a way, because I no longer cared about their reaction, I ended being able to better care about them by delivering a better speech.
Hmmm, that has me thinking that maybe I can apply that to other areas.
