@LuckyGuy Yes, I know you were being sarcastic. And I certainly have nothing against engineering. I am related to three engineers (an uncle, the wife of another uncle, and the husband of a cousin), and I have great respect for each of them. Advising people to go into engineering is certainly a respectable answer to this question. One of the jobs I held before going to graduate school involved working with architects and engineers, and I remember one of the happiest groups of people was actually the apprentice electricians. They loved their job and had a lot of opportunities for advancement.
I just wanted to put in a good word for the humanities, specifically my own field. I was encouraged to go into mathematics and/or science by several of my teachers, but it just never held the right allure for me. While I had all of the required technical skills, I knew I wouldn’t be happy on either of those career paths. I still get to use them: advanced logic is a formal science just like mathematics, making my strong math background quite helpful, and the natural sciences relate to various questions in philosophy. So do the social sciences (one aspect of my work is called “moral psychology”).
As you say, not everyone is suited for a technical career. And the reasons for that can be many and varied. Some will lack the necessary skills and have no interest in pursuing them, some will have the necessary skills but not wish to make a living off of them (or to apply them differently), and some will simply not like the sort of work life that an engineer has. The same could be said of any other field, though, so it is certainly good to be aware of all options.
