Quote of the day by Anna Freud : Human beings spend a large part of their mental energy reviewing their own actions. After almost every decision or achievement, the mind tends to replay events, searching for what could have been improved or done differently. This habit of self-evaluation can be helpful, it builds awareness, encourages growth, and helps people refine their skills over time. But it can also become mentally exhausting when it shifts from constructive reflection to constant self-criticism, making it harder to simply enjoy what one has accomplished.
