We all reach a point in our career where we look back at what we accomplished.  In my case, I have been fortunate to join an industry (mining) supposedly with no future in those days.  People were often puzzled by my choice.  In retrospect, I can humbly say I wish everybody to join an industry with no future!  More importantly, my professional journey has been characterized by a series of encounters with exceptional persons (supervisors, mentors, teachers, students, colleagues, team members, etc…) who contributed in their own way in making who I am today and I am grateful for that.
