Do People Value Chosen Rewards More than given Ones?

The other day, I was watching a trailer for a movie, and one of the characters said something along these lines - "Imagine what we would be able to accomplish if we used one hundred percent of our brain capacity". Fictional movie or not, it's very true.

Without a doubt, the human brain is a very interesting thing, especially in the sense that when we use it, there's so much potential involved. In fact, it really makes me wonder how much brain capacity most humans use during the entire life. After all, many people like to spend their time watching TV and playing video games. Even though there are those who are very studious, when it's all said and done, is it really something they enjoying doing, or do they only do it because they know they have to, such as on a college atmosphere?

In relation to the third bullet point, I find that very interesting, although not that surprising. Also, though there have been incidents where I didn't get enough sleep, I never had trouble recalling memories. Regardless though, I can definitely see how this is the case. For example, let's say that you're in college and you spend around six hours studying for a test. And then when midnight hits, you're ready to go to bed. Well let's just say that you decide to stay up all night and party. By the time the test comes the next day, you'll have trouble focusing, and won't be able to recall your memories. However, when you sleep on your studies, it helps you to store any memories you had during the day.
