The most frustrating situation for parents is when after all the efforts to do a careful upbringing & expect the child with behaviors kind enough but instead parents get the unexpected results. The children with behavior problems like anger do also have "motivation to obey" problem. There's not much you can do as a Parent until your child is properly motivated. No Parenting technique, approach, talk, or change on your part will work until your child is motivated to listen to and follow your directions. Most children don't lack the ability to obey their parents or follow rules, they simply lack the motivation to do so.
