There are many things you can do. First of all learn respect for others. Your parents provide you with a roof over your head, clothes on your back and food on the table. They put up with your immature behavior. That alone demands a lot of respect. Learn to appreciate the things they do for you. Your Mom washes your clothes, cooks you meals, cleans the house you live in, etc. If you don't take everything for granted and understand that it takes effort and sacrifice on your parents part to take care of the family you can easier be grateful and show respect for what they do for you. Some day when you become a parent you will see how hard it really is and what all you have to give up to raise a child.
As for controlling your temper you need to slow down. Breathe deeply three times before acting or even saying something back. In martial arts controlling your emotions is very important. If you can not even control yourself how are you ever going to control your opponent? An opponent who fights with his emotions is very easy to defeat because the emotions rule the actions and an emotional person does not think clearly and therefore makes many mistakes when fighting.
So use your family as part of your martial arts training and learn control and how to stay calm. Martial arts training does not only happen in the school. Training has to carry over to ALL aspects of your personal life if you want to be any good.
There is a book by Forest Morgan: Living the Martial Way. I highly recommend you read it.
