Overindulgence and excess are synonymous with the phrase "overdo a good thing." When we have a good thing, it's natural to want more of it, but when indulgence crosses the line into excess, it can be detrimental. Bingeing on food, drink, or even exercise can have negative physical and mental consequences. Likewise, overdoing a good thing can also refer to doing too much of a good deed, such as giving to charity or helping others. While these actions are noble, taking them to extremes can lead to burnout and resentment. Balancing our desire for good things with moderation is essential for maintaining our health and well-being.
