Why is good sleep necessary in self-management?

Correct answer: It maintains energy and concentration

Adequate, good-quality sleep supports alertness, memory, mood, and the ability to concentrate on tasks. A rested student can plan, make decisions, and control impulses more effectively than one who is constantly tired. Sleep does not remove the need for effort or complete goals automatically; it provides a healthy foundation for effort. It should be combined with planning, study, and other healthy habits.
