I think karaoke is not a negative thing for us, by singing we could reveal the contents of our hearts and can make our hearts happy. because with karoke we can entertain ourselves, doing things we just need confidence high, because with high confidence that we will do everything earnestly. With confidence will not think of any opinions of others.
Confident convincing and included confidence in the ability we have and do something with confidence to face life more challenging. I think someone who does not have self-confidence will have a hard life, they will never be able to step in his life, because they han ya think about how the other person, can not believe in his ability alone
