Short TED Talk: Why 30 Is Not the New 20

Summary:
Meg Jay is a clinical psychologist who specializes in adult development, and in twenty somethings in particular. The main idea of talk is: Don't waste too much of your 20's time with uninteresting work, 'stupid' boyfriends, parties and so on. Prepare to your future, try to find what  you really want to do and try to get experiences in the fields which can be interesting for you in the future.The rhetoric that "30 is the new 20," trivializes what is actually the most transformative period of our adult lives.Our twenties are a time when the things we do, and the things we don’t do , will have an enormous effect across years and even generations to come.

What can listeners learn from this talk?
I think the speaker seems to be talking as if we can control everything. However,  the idea that we can completely control and shape our lives is an illusion. So what listeners can learn from this talk is that the talk can trigger 20 something people like me to  reflect on my life attitude. Am I fooling around? Am I using my time efficiently? After watching the talk, I think what we can do is work within the circumstances in which we find ourselves, do not wait until we are 30. And maybe think about placing more value and basing the happiness not on the outcome, but rather on the process, on the effort we put in toward a given goal.
