how to be a successful parent?

There are no proven ways to be a successful parent. You do the best you can and always always talk to your kids. Listen to what they have to say. Even if its about nothing at all. Be honest with them about everything. When they know that you trust them enough to talk to them they trust you enough to talk to you. And when they ask you questions about life, don't say,"I'll tell you when you're older." or "just don't do it." or "You don't need to know that." They have friends and their friends will tell them. Only you have the ability to tell them the pros AND cons. Their friends are more likely to tell them the pros. In other words, mislead them.

I don't think that you should give your kids everything that they want. That just gives kids the idea that they can do whatever they want because you are going to give them whatever they want anyways. I think that spending time with your kids and teaching them right from wrong is better then buying them everything. If a child grows up today and is respectful that is a reason to celebrate in its own.

Then you will be successfully making him an unmanageable and disobedient kid. If you give everything they want, you are just keep yourself away from the inconvenience of disciplining the child. Take time to make him understand what he needs and not. Make him understand the ethics and sharing. He'll turn out great. Good Luck.

just do the best you can

A good parent loves their children, and to the best of their ability, raises them to be good people and to succeed in life. You provide for them, but you can't give them everything they want, and you really shouldn't. People, children and adults, don't always want what's good for them. But, if what they want is good, you do your best to provide it, and if you can't, you still give them love, which is the most important thing.
