Cаse Study: Tаti's Jоurney Tаti is a sоphоmore psychology major who recently accepted a position as a peer mentor for first-year college students. At first, she accepted the position because it provided a small scholarship and would strengthen her résumé for graduate school. Although she enjoyed helping others, these external rewards were her primary reason for participating. During her first few weeks as a mentor, Tati sometimes felt overwhelmed. She worried about making mistakes and was uncertain whether she had the skills to support new students. Her faculty supervisor encouraged her to reflect on each mentoring session, provided constructive feedback, and allowed her flexibility in how she organized meetings with her mentees. As the semester progressed, Tati became more confident in her mentoring abilities. She formed meaningful relationships with both her mentees and the other peer mentors, who regularly met to share ideas and encourage one another. She began spending extra time planning activities; not because she had to, but because she genuinely enjoyed helping students adjust to college. Eventually, she realized that mentoring reflected the kind of psychologist she hoped to become in the future. One afternoon, after skipping lunch while preparing materials for an orientation event, Tati noticed she was becoming distracted and irritable. She realized she needed to eat before continuing her work.
