What kind of people are drawn towards computer science vs. the hard engineering fields like electrical/mechanical/civil?

I wanted to go into computer science in high school but I had trouble with the more theoretical concepts. In college I tried out mechanical engineering because it was the broadest field. I ended up loving it because I got to work with physical systems and even the mathematical / theoretical concepts made sense to me. I found it a lot more satisfying and intellectually stimulating to design, analyze, and build something real.

Students generally pick their undergrad major depending on their experiences in highschool. The most important factor appears to be the topics a student enjoyed in highschool. Their knowledge about these topics and the nature of engineering curriculum is superficial, but does provide a rough guideline. Many students who go into CS tend to have some programming experience (however rudimentary) in highschool, and really liked it. A different route to CS is through attraction towards more "discrete" areas of mathematics. In the highschool level this include permutations and combinations, probability, and elementary number theory.Students who go into EE/ME etc. seem to have enjoyed physics and the "continuous" version of mathematics like calculus, differential equations etc. One of my friends who really like electricity and magnetism went into EE, whereas another friend who like thermodynamics initially joined ME and later switched to CH. Some experiences and attractions from childhood will also attract students. For example, students who are fascinated by airplanes and things that fly in addition to physics might choose AE. Children fascinated with robots might choose ME (incorrectly).
