I found chores and allowance to be a good starter. After that, I added $5 for an A, $2.50 for a B, nothing for a C, you owe me $2.50 for a D, and $5 for an F.
Then hold their savings for an interest bearing account on the computer. 10% monthly and if it goes over $100 it becomes 10% annually. They learned to hold about $90 to get that monthly and an extra $10 to spend monthly.
They both finished high school under age (18) and couldn't understand that i would not let them move out til they were 18. But, I also told them about being emancipated in court. My son asked me about how to do that. I told him to go and find out.
He paid the $99 court fee and gathered supporters. I could not appear in court with him on that day but wrote a letter to the judge in his behalf.
The judge told him that he gets several request of parents trying to rid their homes of wild kids through the emancipation program, and it was designed for kids just like my son and granted him his emancipation. It was a special mark on their drivers license.
My son was proud and was asked when he was gonna move. He said that he didn't need to now and stayed until after his birthday.
