Reflecting on my own actions and the folks I met on the way, taking a better attitude would help a lot. I was young and had good conversations with different types of people but did nothing with that for close to another 15 years.
We had much of the information then, IMO. And I remember talking with much older folks who were willing to listen to teens/young adults about a variety of topics. I just wasn't willing to say anything. Even to my peers.
I would take a better attitude.
