Answer:
Preparing for and participating effectively in a range of conversations and collaborations with different people prepares people for their future because this allows people to interact with their peers, acquiring knowledge through the transmission of specific knowledge and experiences, and finally through the socialization of people with their peers.
In other words, through collaborations and conversations with third parties, people create social ties through which certain experiences are transmitted that allow the person to unconsciously prepare for an eventual future in which such knowledge is necessary.
