headstrong
/ˈhɛdstrɒŋ/adjective
Insisting on doing things your own way, regardless of what others advise.
Example sentence
- “Their headstrong daughter refused to change her travel plans despite the warnings.”
Softer than 'stubborn' and often almost fond, especially of children and heroines in fiction: a headstrong girl who ignores warnings. The fault is in refusing advice, not in the goal.
