Why do you do what you do?

I am currently in a job transition.  As I search for a sales engineering opportunity, I have done a lot of introspection and identified many of my excellent accomplishments.  I have attempted to articulate them in my resume and profiles.  These accomplishments are "What" I have done.  I am often asked during employment interviews...questions about these accomplishments.  Interviewers are focusing on "What" I have done.  I have rarely been asked "How" I do certain tasks.  For example..."How do you learn?"  This is a great question because it tells the hiring manager a bit about how I approach this important subject.  And a question I have never been asked is..."Why do you do what you do?" I think it is a great question...because this question addresses motivation.  I have thought a lot about "Why I do what I do?"  The answer is best described by an unsolicited, heart-felt phrase I use frequently..."I was born to be a sales engineer!"  I am so lucky to have this "gift" and so lucky to have identified it very early in my career.  This motivation source has resulted in many outstanding accomplishments and is the difference between doing a good job and doing an excellent job.  I hope to join an organization that can benefit from these gifts for many years.  I wrote this blog in the hope that readers can benefit from applying this concept to their own challenges.  For example, branding has become important concept in social media and all interactions.  Your brand might be related to..."Why do you do what you do?"
