Bucking odds means defying or overcoming difficult circumstances or unfavorable situations. The antonyms for bucking odds would be giving up, resigning, surrendering, submitting, yielding, conforming, and accepting defeat. It is important to note that giving up or surrendering does not necessarily mean failure, as there can be value in knowing when to retreat or change direction. Accepting defeat can also be a temporary setback that can help us learn and grow. However, persistence and resilience are often necessary to overcome adversity and achieve success. So, while there is no shame in accepting defeat, it takes courage and determination to continue bucking the odds.
