Why is it that, the reverse action of things is so difficult to achieve...? 

If u get addicted to drugs, it's difficult to stop this addiction...
If u start smoking, it's difficult to stop smoking...
If u gain weight, it's difficult to lose it...
If u start loving someone, it's difficult to stop loving that someone...

Resuming: why is it that the way out, is not always as easy as the way in...?
