I think youve taken jugglers 90/10 rule to the extremes,this is a bit like a 900/10 interaction.Although its good to talk my feeling is that they will start to lose interest after youve told them a story for 5 mintues without them having any input.Put yourself in their situation,your in a bar and someone comes over to you that youve never met in your life and starts giving you his life story....
If you can cut out all the details that they dont need to know and shorten the story down a bit I think its more likely to work,although it does sound a bit liek your trying to impress them which will ultimately lower your value,not DHV.
I guess the only way to find out is to field test...
let us know how it goes
