I watched a series of videos recorded 10 years ago, where different bloggers were speaking to their future selves in 10 years.

The versions of themselves from 10 years ago, carefree and laughing, asked: Have you gotten married? Bought a car and a house? Passed your exams? Are you happy?
Most of their 10-year-later selves have put away their smiles, losing the youthful spirit they once had.
“You cannot have youth and the feeling of youth at the same time.”
