     A habit is any action that we have performed so often that it becomes something that we do almost without thinking.  Some of them are  thought to be bad habits.  People spend countless  hours and  dollars each year trying to get rid of 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.
