Different people have different kinds of habits (习惯). Habits are the things people always do. For example, some people like sleeping late, some people like dancing, some people like watching TV and some like reading books. These are all habits.
There are two kinds of habits: good habits and bad habits. Good habits are good for our lives. For example, reading for one hour each day is a good habit, because we can know a lot of things from it. Bad habits are bad for our lives. For example, sleeping too late is bad for our health, so it is a bad habit. We should take more good habits and stop those bad ones.
