"I'm a common-sense kind of guy"

This quote by Robert M. Parker, Jr. speaks with his approach to life and decision-making. He is recommending that he relies on his own judgement and experience to make decisions, rather than depending on abstract theories or intricate formulas. He is indicating that he is practical and down-to-earth, which he values common sense and practicality over intellectualism. He is likely to make decisions based on what he knows and what he has seen, instead of counting on what he has read or heard. He is most likely to be an individual who is not easily swayed by the viewpoints of others, and who is positive in his own judgement. He is most likely to be a person who is not quickly intimidated by complex issues, and who is willing to take dangers and make choices based upon his own experience and intuition.
