People
Mide and low made the excellent point that you are investing in the people. Judge character by impression only and you aren't looking at all of the pieces to the puzzle. You step back, observe, listen, understand it's type, motive, weakness, strength, etc. in order to see through to it's core, to size it up.
Hard to do in a video and not in person but I am thankful for what I got since I could not attend.
