Are restrictions good? Do they help you grow or tie you to a certain place and stop your growth? Restrictions are of no good. If you have the means but then you are not able to use those means then there is no use of having those means with you. It will always mean that you have the wings but the wings are tied so tightly that you will not be able to spread it and enjoy the sky.
Restriction in any form is not good. It narrows your perspective and misdirects your vision. You are not able to see things properly. A lot many opportunities get lost when you are being restricted. One must have seen parents putting restrictions on their child and the reason which they give is that they are protecting them. Well, they forget that in that process of protection they are indirectly keeping him into a bubble of comfort which would one day definitely burst leaving that child vulnerable and directionless. Also, restriction is the major cause of rising hostility between a child and a parent. The child feels that his mother or father does not understand him and are not compatible. He starts resisting them and distances himself from the love and care of his parent. He feels that his needs are ignored and his identity is being supressed.
So what is the outcome of this?The child resents the norms of the parents and lies and mistrust takes the place of truth and faith. The first successful lie that he tells makes him believe that he can do all sort of restricted things and can easily hide it from his parents, and after this comes a series of lies. The child feels that the restrictions were baseless as none of the forbidden things was harmful.It would be much better that instead of putting a line of restrictions, what the parents can do is that they can talk to their child and sort things out. The best way to solve this is to become friends with your child as your child should tell things to you not because he is afraid of you but because he feels that you are his friend and so he can share all his feelings with you.
Also there are people who puts restrictions on themselves. A fat person restricts himself from eating all kind of food so that he turns slim and fit and easily lovable. Also one can find all sorts of person who can be found restricting themselves for one thing or the other. But the most important thing is that you do not have to restrict yourself or others but feel free to do things that make you happy.
