Adsense doesn't make me much money

I have been unable to blog for a long time because of various school-related responsibilities and stuff.

I just checked on my Adsense earnings to see if my site was making any money in my absence. Unfortunately, since I first started using Adsense in April of last year, I have only made $15.

That means that I haven't even gotten a check from them, because they won't send me money until my balance reaches $100.

I am hoping that at some point I will make some more money here, because it would be nice to have a source of income that I needn't work hard for.
