Why 30 is not the new 20

Meg Jay is a psychologist who gave a talk about how wrong are people about the concept that the 30s are the new 20s. 

In this talk, she talks about things like work, studies and marriage, things that usually people used to do when the were in their 20s. But nowadays the thought we have about the 20s decade is seen as an irrelevant period of your life when you can be independent and don't worry about important stuff. 

That's why Meg Jay tries to explain that they're wrong about this, because it's in these years that we became the person we will be as an adult and decide how our future is going to be. Also, she says that It's much better make these decisions as earlier as possible because if you don't, you'll see everybody else settled and you'd want all the things that they've achieved but maybe you won't have time.

Personally, I agree with most of the things that she said, but Meg seems to make us believe that we only have to organize our future and make these importants decisions, when I think that It's not all about that because we're still young and we have to enjoy life and have fun.
