Do not make your child insensitive...
With every passing year, we should have better control of our children. But actually we lose control as time passes by... 
Child's behaviour cannot be improved by shouting, constant nagging, through physical punishment or by unnecessary false threats ('injections', 'Police', 'locking them in' or 'sending them to a far place' etc).
As we love children, they also love us. Whenever child is not listening to you or obeying, you should show your unhappiness until child realises. Sometimes few hours or may be for days, you must maintain your stand.
Do not lose your stand at meal time...
Or may be next day...
Do not wake him up for school or pamper him until he realises his mistake...
If you want him a good human being and successful, he has to learn to care for others...
