The phrase "wrought oneself to the bone" indicates physical or mental exhaustion from excessive effort. Its antonyms would be "relaxing," "resting," "taking it easy," "slacking off," or "unwinding." These words suggest the opposite of exerting oneself to the point of exhaustion. One can rest, recharge, and rejuvenate to become more productive and efficient. Being idle for too long is not recommended, but taking regular breaks and engaging in activities that reduce stress can lead to better health, happiness, and performance. Therefore, it is essential to balance work with leisure and avoid going overboard with unnecessary stress or strain.
