income is definitely something to consider when choosing a career. civil engineers earn a yearly median income of $78,000, while pharmacists earn a yearly median income of approximately $112,000. however, there is more schooling involved with becoming a pharmacist. pharmacists must earn a four-year professional degree in addition to a bachelor’s degree, and civil engineers need only have a four-year bachelor’s degree. because i enjoy school and would like to earn more money, i am leaning more heavily toward becoming a pharmacist.
