I don't want to screw over my own kids
Thats good. What makes you say this though?
Because I know what nobody should do to their kids, and I would never want to do that to them.
It's very good to you to not want to cause them harm. It's important to realize that kids need to be protected.
Do you think I'm doing the right thing?
Yes, I think you're doing a great job. As their parent you have control over what happens to them and its important to prepare them to take care of themselves as they get older.
