The Rene Descartes' quote says that it is not enough to be intelligent but efficiently use that intelligence.
Intelligence is a complex of psychic and mental faculties that enable humans to take actions in different fields. We may have one kind of intelligence, such as linguistic intelligence, but not interpersonal intelligence, or vice versa.
We need not worry about not possessing high intelligence because it is not strictly necessary. It is, however, a helpful element for work.
Moreover, possessing a certain kind of intelligence does not mean that we can do well in a particular environment. Many other essential elements come into play, for example creativity, manual dexterity, and so on.
