Overwork is when you do too much work and don't have enough time for rest or fun. It is important to avoid overworking because it can lead to feeling tired, stressed, or even getting sick. When you are overworked, you may have trouble getting enough sleep, have trouble concentrating, or feel like you never have time for things you enjoy. To avoid overworking, try to plan out your time so that you don’t have too much work, and make sure to get enough rest and have some fun.
