Industrial Salesman Seeking Transformation: How to Relax and Relate?

I am an industrial sales professional, with wide experience working with Indian owned companies, US MNC and now working with a US company in the US. I went through complete transformation in my style of working. From being casual happy go lucky young salesman to nearly perfectionist, sharp and 24x7 thinking salesman now. As the organizations changed, I adapted the work culture. As I grew up in the ladder, more and more passionate I became. I expected everyone to behave professionally even people out of my office and in general life. Be it a shop owner, plumber or a gardener. It is like Amitabh Bachchan as a head of Gurukul in a movie. To the extent that my wife and daughter are also experiencing my professional behavior at home. At a stage when I want to become relaxed and slowdown, leave some things to normal course, I am caged in my corporate behavior. To tell you more, I am a Cartoonist also and can find humour from anything that I see. But, my cartoons are also based on the product line my company manufactures. I am doing a lot of meditation, taking a walk and playing with my dogs but unable to change myself. How can I go back to my original self so people around me remain relaxed when I am around?
