Rights and obligations

How often do we turn our rights into obligations, while killing something intangible in the process?

The right to go to the gym a few times a month becomes and obligation to lose X pounds by date Y.

An “all you can eat buffet” - an absolutely striking example - which for some (many?) becomes an obligation to try out all there is to try out there.

The right to the pursuit of happiness becomes and obligation of always thinking positively and looking at the bright side of life, thus creating “Prozac nation”.

You have the right to keep your opinion to yourself :)
