Discipline is temporary !
Discipline is something which can not be spoon fed or taught, it is something which comes by itself. Discipline is reflected from the mannerisms or the manners of a person, the way a person dresses and by the way he/she talks with others. If anyone is willing to make you disciplined, he will have to do it by training you but it will not last long .
You can be disciplined only when you make it your habit or when you make it a part of your routine. Discipline can be achieved by being strict as well but it will be of no use, that will be never lasting. It will last hardly for a day or two. Discipline achieved with the aid of strictness is like training a lion to sit. You can never force someone to be disciplined until and unless he or she is willing to be.
Parents train their children in such a way that they seem to be disciplined and that kind of discipline is permanent which is a result of training given at home and that is something that matters.
