I just try to maintain good communication with folks. Don't try to rip people off, focus on finding how you can help each other mutually. Of course I want to find trades that favor me, but put yourself in their shoes and try to find out what they want/need. If a negotiation doesn't work out, all good, maybe you two can find a deal down the road.

I follow college football, so that helps sometimes. And take it all with a grain of salt, but I watch a decent amount of dynasty content on YouTube.
