Research suggests personality traits play a significant role in determining happiness, outweighing daily experiences. Nearly 80% of an individual’s life satisfaction is tied to specific character traits, with extroverted and assertive qualities being linked to greater contentment. The findings, consistent across different nationalities, challenge previous beliefs about the impact of personality on well-being. Research indicates that while experiences can influence happiness, they tend to have a more general, long-term effect rather than immediate changes.
