Should I leave?

As you know, since Summer begun I have been working. In the first month, I will only receive committees of my sells, but I haven't reach the goal and I ended my month with 0€, until here is normal, because I had only 11 days of work.

This month, I haven't reach the goal again, but the deal was, if I didn't reach the goal I would receive the committees... but is August 6th and I have no money in my account. My mom says that I should quick and enjoy the rest of my vacations, but I don't want to do it, because I want to have my own money... what would you do if you were in my place?
