crunching the numbers

I've been looking online for a child to sponder either through food for the hungry or world vision (or both!). How do you just pick one!? I've been looking at three kids I desperately want to sponser and it seems like the more I look, the more I want... I've been working through my budget trying to see if there's any way I can sponser more than just one kid, but right now it looks like I'll only be able to sponser one. I could possibly bring on another child in the fall when I'm back working in the chem lab in Lincoln but usually during school I only make around $50 a week (I only have time to put in a few hrs) and that's not a lot when I'll be paying for groceries, shampoo, toothpaste, toliet paper ect. Grrr. I guess for now I'll just keep setting aside more and more money and hopefully I can make it work. Keep me in your prayers as I continue to work on my relationship with Christ, I'd really appreciate it!!
