A habit is any action that we have performed so often that it becomes something we do almost without thinking. Some of them are thought to be bad habits. People spend countless hours and dollars each year trying to drop these bad habits but often fail. Why? Change is hard work and there is no shortcut to achieve it. However, there is still some advice for you to follow.
First, look at why you do it. In other words, what’s the result of doing this thing? If your bad habit is shouting at people when you are unhappy or under pressure, what do you get from it? It may make you feel a little better for the moment. Or maybe you have a bad habit of leaving your homework undone. The result could be that you get more time to spend on the Internet!
Next, take a look on the other hand. What are you losing because of your habit? Shouting at other people is a bad habit because it makes people around you feel bad and unhappy. Leaving your homework undone is a bad habit because you may be punished by your teacher. Having more Internet time means that you are losing the chance to learn the things that you need to learn. When you think that way, you’ll find that it’s not wise to keep your bad habit! Now it is time to make a decision. What will you choose? I’m sure you will choose to do what you think is more important.
