Compromise

Life is a compromise. At no point does a person get what he wants. Even if he gets something that he wanted badly there would still be something missing or something he has to give up. Sometimes compromise is the consequence of the rules imposed on the person by the society.
A person who can accept this will have lead a peaceful and happy life while it will be nothing but turmoil, discontent, contempt, dissappointment and bitterness. Some people realize this truth but are unable to accept this and try to figure that there should be a way to disprove this unwritten rule but only in vain.
Why does it have to be this way is a question which might require more than a lifetime of research or rather search.
