Well, I know this is going to sound cliche', but try and give what i'm about to say some thought..
There are no "magic" words, lines, or stories that you're going to tell her to make her fall in love with you.. Now, since that's the case.. it doesn't make sense to feel this pressure of "what should I say to her?".. Honestly.. just be able to talk.. have "moxie".. and have a normal/natural/just-the-way-you-are state of mind..
Voice Tone: (work-out) Make a small little speech about how it takes energy to break bonds, and how energy is released when bonds are formed.. write this speech out, go into a little detail about potential energy.. keep it simple.. about a paragraph or two.. Type it up, and start to say it to someone (a friend, or the wall).. Keep saying it.. and try and notice how you're feeling, the tone and quality of your voice.. the speed and the pace.. the rhythm.. everything.. and as you notice these things, and get more smooth and natural at it.. try and notice how comfortable you feel when you're talking about such a neutral subject.. to such a neutral audience (your friend, a wall, etc).. and in all honesty.. when you're talking with "her", just rest easy knowing that nobody is judging you.. seriously.. just like your friend, or the wall..
When you get bored of your speech.. try saying "I pledge allegiance to the flag".. the whole thing.. over and over again.. And get used to your normal, relaxed, care-free, all natural voice..
What do you talk about?
- Anything
Seriously.. you can talk about anything.. Milton, classical mythology, art history, toasters, anything.. anything.. ANYTHING..
I would sit here, telling you some stories to have in mind, what to memorize.. but all of that is fake.. don't memorize anything.. start off with a "hi".. and take it from there.. talk about whatever comes your way.. talk about it naturally.. and don't sit on the same subject for too long.. switch often.. only go back on topics if she asks you to.. and talk with your natural voice quality..
Keep your conscious mind clear, there's no thinking.. there's just doing.. there's just feeling..
- And if it doesn't happen exactly the way you want it to.. that's ok.. and i'll tell you why.. because you're growing.. it's a learning experience.. the best thing that can possibly happen, is you doing something wrong.. and you'll learn to not do it next time..
When you look at it that way OV, you can only either gain a relationship the way you like it (depending where you want to take it).. or a learning experience.. either way.. I hope you realize that you win both ways..
And with that in mind.. the only thing you should remember, besides your natural voice quality is.. there's no thinking.. there's just doing..
PS. If you find this the least bit helpful.. I always listen to Cat Stevens "The First Cut is the Deepest" just before I go out to talk to "her".. I close my eyes and sing along.. loud.. until i'm laughing.. smiling.. completely comfortable, up-beat, and ready to go out..
Best of luck OV, and hey.. remember.. just have fun..
