How Can I Fight Laziness?

Lazy people will never amount to anything in life. However, laziness can be defeated once a few changes have been made in your mind.

___小题1:____. Many people lack sleep constantly, since they stay up too late and get up too early to prepare for work. These people have little motivation once they arrive home.

Others in the home may eventually follow your example and perform their own task. It is difficult to practice laziness when you are surrounded by motivated people.
