Indeed. You don't need "a good, respectable career" to have a good life. Even if you wish to have a life containing moderate wealth, you still don't need that. (Up to you whether you believe that moderate wealth is either required or desirable for a "successful" life)
And even if you want "a good, respectable career", there are many paths to achieving that goal as well.
I feel that we have allowed too much "program thinking" to control our school-age children. We put them in the best preschool program we can afford, then run them through a carefully managed elementary program, finally we push them into an elite-college-prep high-schools program and then enroll them in a university degree program.
Afterward, is it a surprise that these kids graduate and expect to find pre-mapped "programs" to follow for the next part of their lives?
And bigger companies know this and will oblige -- intern programs, of course, and then new-grad programs and well-tended career ladder progression with a performance review program.
None of this is bad by itself, but it is unnecessarily limiting to look at life as a series of programs. It is allowing others to define success for you. Which is easy -- because deciding what the eff you want out of life is hard -- but it is so limiting.
Even if what you end up doing looks kinda like one of the programs, choosing the path yourself is so valuable.
