Harmonious passion is adaptive

• Harmonious passion for sport predicted more positive sport experiences, such as higher goal attainment, sport enjoyment, positive emotions, and academic satisfaction.

Perfectionism is pointless

• Striving for perfection in sport, beyond striving for excellence, was unrelated to performance or experiences in sport throughout the season.

This research showed the value of pursuing sport with high levels of harmonious passion, an intense motivation that is also a balanced part of one's life.

It also failed to show any benefit of being a perfectionist in sport.
