My 3 years old son has become very stubborn...doesn't listens to me or his dad unless we shout at him. We tell him don't do he will do it and show. How do I explain to him?

Shouting is just a quick fix... but never works in the long run. I just try to explain to him the consequences of his actions and how I will act upon it if he isn't listening. Then I go right through with what I said. No more game no more story at bedtime no more toy etc.
