Antonyms for "applying oneself" refer to the opposite action or lack of effort. These include procrastinating, slacking off, neglecting, avoiding responsibility or duty, idling, and being indifferent. When we fail to apply ourselves, there can be consequences such as poor performance, missed opportunities, dissatisfaction, and lack of personal growth. It is important to recognize and address any tendencies towards avoiding effort and taking action to overcome them. One way to do this is by setting achievable goals and working towards them consistently. We can also seek motivation from within or external sources to help us stay focused and committed to our endeavors.
