"When my Dad passed away I went through a phase when I got really mad at myself and other people, when it was something I couldn't control. So that is probably my biggest message - anger is a waste of energy," Adams said.
The Kiwi star said he finds it strange to be seen as a role model for young athletes.
"It is really weird, but most of the stuff I have to share with them ... it's stuff I picked up along the way from veterans and more experienced players that have given me their time and helped me out."
Joining Adams at the event at Trusts Stadium were All Blacks Liam Messam, Aaron Smith, Julian Savea and Tawera Kerr-Barlow.
Adams returns to the United States at the end of the week, but will be back next month to host a NZ Basketball Academy camp in Wellington.
