Raising a child is hard work, when they are a tween or teen it is even harder. My wife and I found a better system called Love and Logic that made it a bit easier. It would have been nice if we learned it earlier.
Our son is in college now and helps us out, while I help him with homework and edit his essays so he gets better grades.
Since 2003 I've been on disability and been mostly a stay at home dad while my wife works. I taught my son how to fix computers and build them. He fixed his friends computers and then learned how to fix cars, ECT.
I would go through it again if I had to.
Not everyone is cut out to be parents and children can vary, as you never know what you are going to get.
