Find a story that really hit's the nail on the head with what you want to do with him, and show it to him. Tell him something like "I read this story and just wanted to show it to you cause it's really hot. " Then gauge his reaction. If he agrees, then ask if he'd consider trying it with you. If he seems unsure then just say "I don't know how you feel about it, but I think it looks kinda fun to me." If you don't wanna come right out and hand it to him, maybe you could print it out and "accidently" leave it in the printer? Good luck!

Complete surrender should not just come at moments in which one faces overwhelming odds, but in the calm when it seems one is personally in complete control of one's life.
