During a Moneythink session at a Chicago high school, a mentor from Northwestern University discussed breaking down paychecks into spending money and savings. One student, Jovanni, said he would save all but $100 of each paycheck. The mentor promoted using SMART goals for savings. Jovanni recalled impulse buying from peer pressure in the past. The mentor explained the benefits of saving in a bank account versus at home, like earning interest, and discussed using savings for future expenses like college, emergencies, vehicles, homes, and retirement. Mentors worked with students on a worksheet about compound interest over time. They emphasized the importance of professionalism in attire and posture to show respect.
