Denial doesn't help.

Many of the time people tend to hear only the good stuffs and dispose of all the thing that is bad and of facts. In reality, it is good to listen to both the pros and the cons before jumping into conclusion. In any ways, use the law of attraction in moderation. It doesn't means that just thinking only about the good stuffs and ignoring the bad stuffs will give you good results. But thinking positively as well as realistically will help in many ways.
