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