Living off of is often used to refer to a situation where someone is solely dependent on something, typically financial or material support, to sustain their livelihood. However, there are several antonyms for the phrase, which describe independence or self-reliance. These include, but are not limited to, self-sufficient, self-supporting, self-sustaining, self-standing, self-reliant, and self-efficient. Living off of someone or something can be seen as a form of dependence, while being self-sufficient and self-reliant implies freedom and autonomy. These antonyms serve as a reminder that it's crucial to strive towards being independent and self-reliant in life, rather than relying entirely on external support.
