The skepticism of youth signals the beginning of a search for something actually worth trusting, both within one's own psyche and in the world. That's why teens, supposedly stuck in life's lost years, are often so unequivocal about what they love and what they hate, and so frustrated when they feel misunderstood. The adolescent spirit is not the spirit of the lost. It is the conviction that you are not lost — that wandering has a purpose, and that what you deserve more than anything is the freedom to walk awhile on your own path.
When you're young, you always think you'll meet all sorts of wonderful people, that drifting apart and losing friends is natural. You don't worry, at first, about the friends you leave behind. But as you get older, it gets harder to build friendships. Too many defenses, too little opportunity. You get busy. And by the time you realize that you've lost the dearest best friend you've ever had, years have gone by and you're mature enough to be embarrassed by your attitude and, frankly, by your arrogance.
What a mistake to suppose that the passions are strongest in youth! The passions are not stronger, but the control over them is weaker! They are more easily excited, they are more violent and apparent; but they have less energy, less durability, less intense and concentrated power than in the maturer life.
