As a child, I was rewarded for certain things, and punished for others. And that is why In my adult life, I tend to do some things more often than not. I do not tend to sleep late, as I would not get rewarded for doing so. However, for doing chores, I would get rewarded. Although I no longer get punished or rewarded for these things. In my adult life, I tend to still do them out of habit. It is very cool to see that this is a psychological phenomenon.
