Life's unfair.

I'm getting totally pissed off because of my brother. So he's 17. He has had his exams and he has had vacation since, what could it be, a month already. He hasn't done a sh*t since then. All he does is sitting in his room, either watching soccer or playing FIFA 2012 on his computer. Like really? I know I'm addicted to computering, but even I've done more, not counting school and studying with it. My brother hasn't even been outside this house since a week or two. Like really, I lock myself up in my room but I DO go outta the house with my mom often. Oh and I open my window, and he doesn't. And he's so selfish these days. But last time, my mom went totally mad that he didn't have a job yet, so now he's going to work at the EM-TE, some supermarket near my house. So yay, he's finally going and he'll finally earn his own money. >.<
But my brother's lazy, but I WANT a job. I really do. I wanted to work at a kennel, they said I was too young. Fine yes, I'm young. But I want a job. I want to earn my own money. I want to buy a piano myself (and yes, I know that'd take ages if I'd take a piano from about 2000 euros. But I rather pay a part of it myself and that my parents pay the other part than that I don't pay for it at all, I just want to show my parents I want this).
I just want to reach things, such as.. Well.. I just want to become a pianist and a singer. I love the piano, I love singing. I can't live without it. If I'd become deaf, I wouldn't want to live anymore. If my voice would fade away, there wouldn't be much fun for me to have. I just want to show my parents, somehow, that I really want all of this.
