I searched on the Internet to understand what "Opportunity Cost" means, I'm still confused. Like " Assuming the best choice is made, it is the "cost" incurred by not enjoying the benefit that would be had by taking the second best choice available". So basically, you are not choosing the first option which is believed to be the best option but you choose the alternative because of the cost difference between the two?
I'm thinking this is the unlimited wants and needs from a human being versus the limitation they get with available resources - like time, money and other people's interactions with it.
Can an economist shed some light and give me an example, please?
