It is interesting that you bring up LIGO. I actually had a formative experience in my career around a decade ago related to this. I worked on the project for a summer. During that period, I realized that the process of discovery in the dark is one where the seekers have no control over the treasures. I decided not to pursue a career in the field. My lotus of control could not handle dedicating my life's work to chance.

Rainer demonstrated a dedication and passion in that interview that not everyone can meet. I learned that I'm more passionate about effective/real world problem solving than I am about physics.

Those who have a true passion for physics have my complete support and admiration. You're doing great - keep at it :)
