Broke College Kid.

So... this is more of a rant than a useful blog post. But i'm sure MANY of you can relate.
Have you ever noticed that people say "money doesn't make the world go round" but it totally does? I mean, without money you're homeless, hungry, and have none of your basic needs. Well, I have to say that I am very blessed. I have a roof over my head and simple luxuries - my own car, an iphone, wifi at home, my own laptop, etc.  But, as a college student without a job - because I'm focusing on my studies not trying to do too much at once; I'm constantly struggling with money. I want to shop or get a Starbucks, or get my nails done and I'm BROKE.
I started trying to sell things on ebay and poshmark, but nothing seems to be selling. A lot of people are selling and not buying, and some weeks I make a few dollars but not much. So, if you have any money making tips at home, that aren't getting a real job, I would love to hear them! I have tried to do surveys, but since I'm not the main decision maker in my household, I don't qualify for a lot of them. I've even tried babysitting, but i haven't gotten lucky there either.
So please, let me know if you know anything that I could do!
