How are 20s different from 30s?

Your 20s are hard, but being in your 30s presents a whole new set of challenges. People in their 30s are expected to achieve more and find themselves going down life paths different from their friends. But your 30s bring a greater level of self-awareness, too.

Do you feel different in your 30s?

One study found people dont feel truly happy until the age of 33, due to a combination of living in the moment and worrying less. Around 70% of those surveyed hit their happiness peak then, compared to 6% in college years and 16% in childhood. Over half of us believe life is more fun in our early 30s.
