"I believe that we have been doing this not primarily to achieve riches or even honour, but rather because we were interested in the work, enjoyed doing it and felt very strongly that it was worthwhile"

This quote by Frederick Sanger talks to the idea of intrinsic inspiration. He is recommending that the primary motivation for the work he and his colleagues have been doing is not for the function of achieving wealth or acknowledgment, but rather because they are genuinely thinking about the work and find it satisfying and meaningful. This concept of intrinsic inspiration is an important principle in psychology, as it suggests that people are more likely to be successful and productive when they are driven by their own internal interests and worths, rather than external benefits. Sanger's quote is a pointer that when we are passionate about something and think in its value, we are most likely to be effective and satisfied in our work.
