Money making?

Hey peoples. I finally was able to get a cell phone, but it's a pay-as-you-go phone and I have to pay myself. That's great, I mean, I'm really happy I FINALLY got a phone. (Not like those brats who say "Woe is me, I have a crappy phone!") But I'm afraid I'll run out of money to pay for my phone. What are some good ways to make money (throughout the whole year)? Also, it will get you a better chance for best answer if you give out a few pointers. Thanks!
