the way I see it is it's like in the matrix you've already made the decision.
you are a product of everything that has happened in you life. if something happens you will react a certain way.
all you can do is with the now you could read some pick up material, pick an outfit decide where to go. These are controllable variables.
when you meet concentrate on your body language more than anything.
maybe you could write down some conversation topics.
check out some funny shit on the internet so you can talk about it.
e.g
Pointless Sites - Useless Sites - Random websites - PointlessSites.com
just remember keep it on positive things cos when she's looking back on the interaction you don't want it to be about fears of the collapsing economy.
talk about beautiful things.
