Self-control is not only about control oneself, but also includes the ability to eliminate interference from irrelevant stimuli and persist in completing related tasks (even tasks that one does not like). There are different views from various schools in academic circles on whether self-control is stable  and unchangeable  or can be consumed. Psychologists divided the experimental subjects into two groups and asked them to solve problems in the same field. One group could only eat radishes when solving problems, and the other group could also eat biscuits. As a result, the group that only ate radishes gave up earlier because they not only resisted the temptation of biscuits but also consumed self-control. From this, psychologists conclude that people's self-control is limited, and overuse of it will lead to a decrease.
Biscuits and radishes have different allures to test subjects should be added as a prerequisite for the rationality of the above conclusion.
