There has never been a time where that statement wasn't more true. Society is inundated with the need for immediate self gratification. Somehow this is related to previous generations experiences of having to do without and sacrifices made. We have become a society that feels so entitled.
Somehow, we seem to have developed a need to recuperate. It's really very stupid and undermines all that is really important. It will be the end of us .. mark my words.
Some people are usually so much self-centered when it comes to things they don't need because they usually have a feeling that everything should revolve around them. They think everything should be colored with their own self-interest. Individuals who are always useful to them are normally given more importance, yet very important matters that don't relate directly to them are usually given little attention.
