how to find a job quickly?

I've started looking for a job a couple of weeks ago and day by day I'm feeling more useless 'cause I can't find any and the people I've contacted doesn't even bother to replay. My family and friends are trying to be supportive but they have jobs so saying "it's easy, you're just not working hard enough" is kinda depressing. I can't believe myself I'm venting out here but I don't have anyone to talk about it, really.
