I'll agree with everyone else's comments and suggestions. However, I'll add my own.
Like Old Bob this made me ask, "who else lives in the house?"
Well you need to figure out this 'unknown reasons' and do something about it!
Here's a few tips:
-Be clean-shaven and have tidy hair and nails when you go to an interview.
-Make sure your breath is pleasant and that your teeth clean
-SMILE and maintain good (but not creepy) eye-contact
-Behave confidently but also very politely
-Be friendly
-Have answers to the more common questions 'planned out' to some degree.
-Dress professionally (not what you would wear if you were hanging out at home or visiting friends)
-Market yourself! Be enthusiastic and excited about your skills! Talk yourself up without sounding like you're bragging.
-Be interested in the job and even the potential employer! Ask questions. React positively to what he/she tells you. Seem interested and excited about the job, the opportunity, and the people you would be working with.
-Emphasis your willingness and eagerness to learn and adapt. I.E. "I know I've never done X before, but I learn very quickly and this is something I've wanted to try out since I was a kid. I feel like this is a good/interesting/useful thing to be doing, and I'm really looking forward to trying it out!"
Also, do not give up! Don't go on one or two job interviews a week and think 'I can't find a job', make it a point to apply and interview for at least one or two places a day.
Can he ask for more hours?
Geez! If he's getting robbed half the time he might want to look for a new job as well!
What about rent/housing?
I agree that the most expendable thing is the TV. I mean geez, 50 dollars a WEEK? I don't watch TV so I don't really know, but it seems like you could BUY a TV outright for 50 bucks, or at least a 100 or 150 (so send it back now, do without it for two or three weeks, save that money, then go and buy one). It may not be the nicest, flat-screen, giant, Hi-Def. type, but just buy a cheap TV for now and when your situation gets better you can upgrade then.
Good luck, dude,
Kevin
