When we ask our father for some money, if he asks us to take it from his pocket, he has given us a right to take money from his pocket. We should be responsible to take the amount that is exactly needed. If you take more than required that will come under misuse and next time you may not be given that chance.
We should always perform within the specified limits only. When you have a right, there will be a description for that right and you should be within those limits only. Otherwise, it will be treated as misuse and you will be questioned.
But when we have the right to make a decision and if we are not taking the decision, that will have a say on our performance and many times not taking a decision will also be treated as a misuse of rights and responsibilities.
Opportunities, rights and responsibilities are being discussed in this thread. I agree that suitable opportunities rarely come to an aspirant of opportunities. He should be agile and aware of what is happening around in market for job opportunities. He should keep his eyes open to catch suitable opportunities.
As far as rights and responsibilities are concerned both are intertwined. My rights are responsibilities to my friend and his rights become my responsibilities towards him.
We should not think about our rights only, rather we should first think about our responsibilities.
