Rethinking career advice: beyond "follow your passion" for physics students

I started reading a new book a few days ago: "So Good They Can't Ignore You: Why Skills Trump Passion in the Quest for Work You Love" by Cal Newport. Having read many self-improvement books before, I can confidently say that Newport's book has already changed my perspective on my professional career and career development in general. Reflecting on my journey thus far, I would like to share some advice with readers of my physics education blog.

Many of you have likely chosen physics (or a related subject) as your major because of a strong high school background or a fascination with big questions about our universe. For me, the latter was true in particular. I was drawn to astrophysics due to my love for documentaries about black holes, science fiction movies, and the job prospects physics offered. Motivated by my passion for astrophysics, I began my undergraduate studies in physics.

Why study physics and not engineering?

Nowadays, more and more people seem to be asking the question "Should I study physics or engineering?" 

From my experience in the United States, engineering majors such as electrical and computer engineering (ECE), mechanical engineering, chemical engineering and aerospace engineering are extremely popular with young people. As an engineering student, your future career options are relatively straightforward, since you become an expert in a specific field with a great selection of potential employers in industry. In other words, as an aerospace engineer you will most likely end up in industries in which you design and build aircraft, spacecraft, satellites, missiles or related applications. No big surprise. Certainly, this is also true for the German system as well as for the rest of the world.
