The term that describes someone who consistently puts others' needs and well-being before their own is "selfless." A selfless person is often described as being compassionate, generous, and caring, as they prioritize the happiness and welfare of others without seeking personal gain or recognition in return. Selfless individuals may go out of their way to help others, often showing acts of kindness and empathy, and they may find fulfillment in the happiness and betterment of those around them. While being selfless can be a positive trait, it's important for individuals to also take care of themselves and find a healthy balance between helping others and attending to their own needs.
