What was one ideal of renaissance humanism?
(1) training as a knight and practicing chivalry
(2) obeying divine right monarchs and the
church
(3) living apart from the world and taking
monastic vows
(4) investigating areas of interest and fulfilling
one’s potential

I believe the answer is: 4. Investigating areas of interest and fulfilling one's potential

Renaissance humanism inherently promoted self actualization. This view advocate people to not conforming to societal standard, but rather trully focused on our own passion and talent. By pursuing these passions, people wouldn't mind putting large work/training hours to a certain task or skills, and people would eventually achieve high level of satisfaction in their life and fulfill our own potential.
