Teenage years are like trying on outfits to see which one fits best, according to my
psychiatrist. So there is, perhaps, some instability that will be outgrown with experience, education, and insight.

They're wrong, unfortunately, about adulthood being an age "when everyone gets along and everything suddenly turns into sunshine and rainbows", as you say. Honestly, are you sure you didn't make up that statement? It sounds a little like a teenager's way of putting it.

Adulthood is going to require maturity--a use of the reasoning capacity, a sense of one's own self as being responsible and yet vulnerable, and therefore a bit humble.

Do you know why no one is permitted to run for president of the United States until he reaches the age of 38? It has to do with the supposed idea that by being 38 years old, one has become mature and has a sense of reasoning.
