The term "time wastings" refers to activities that consume precious time but do not yield any productive outcomes. The opposite of time wastings would be activities that are productive and efficient. Synonyms for such activities could include "time-saving", "efficient", "productive", "effective", "useful", or "practical." For example, instead of wasting time scrolling through social media, one could engage in productive activities such as reading a book, meditating, exercising, or learning a new skill. Avoiding time-wasting activities can help individuals accomplish more in less time and lead to a more fulfilling and successful life.
