I have no direction in life and i'm lacking motivation. What can i do to improve my situation, advice please?

Hi, I'll get straight to the point. I am a 23 year old lad and im pretty much on a downer most of the time. my dad is always naggin me to get a job, but i really cant be bothered to search for one. I have no motivation to do anything and i hate startin work at new places because im a shy person. Also, i have no direction in life, most of my mates have good jobs, and then there's just me who hasn't got anything going for himself, and i just get so depressed. I'm single, never had a girlfriend and most probably i'm a mive turn off for girls when they know i don't do anything or have no desire in life. I left college ( UK ) 2 years ago with a Diploma (A level equivalent) in something i now don't want a career in. I am so confused and depressed about my life, and my future looks bleak! I wanna move out, i wanna drive a nice car, i wanna have a good job, a girlfriend and travel places, but how can i do that when i have no motivation to do anything. My days consist of waking up at 12 noon, having lunch, browsing the internet, maybe apply to a job or two online (i have to force myself), play PS3, have dinner, browse the net until early morning, go bed, and repeat the next day. It's so boring, i know it's boring, but i have no motivation to change my situation, even though i need money to go out. I have been living like monk for so, so long now, that it's getting frustrating. I need a mive kick up the a$$ to do anything, it's ridiculous! I mean i watch these guys who are successful and money driven, they're successful, powerful people, and i want to be like them.
