Eating healthier foods
Explanation:
There are many things, such as social, behavioral, and biological factors, that can affect the way we feel about life. In the given scenario, we have Harriet, who has made some changes in her life that make her feel better. She made new friends and found guidance from community leaders, which can be defined as a social influence - an influence originating from interaction with other people. She also introduced a new behavior to her routine - writing about her daily achievements. This is healthy behavior, as she is reminding herself about the good things she has done and additionally motivating herself. The only change that can be described as a biological influence is the change in her diet - she started eating healthier foods. This directly affects her body and makes her feel generally better.
