Create new biz relationships now. Promote your projects. Attain the affinity part by sharing recreation, games, sports or meals, going to the movies, etc. with biz pals. Create the event. Remember, recreating together is the highest thing two people can do.
Affinity is based on recreating together.
Recreation creates loyal friendship, rare in business and quite useful. Make a list of relationships where there's either friendship and fun or shared work. You see that the missing element gets added. Share recreation with someone with whom you already share work. And, plot some business you can do with someone you already share fun and games with on weekends.
