One exercise I do is something I call the Three Choice Technique.
Three Choice Technique
1. See girl.
2. Think: What would I say? How and where would I stand/sit/walk?
3. Imagine doing it and what would happen (this is called 'Ecology Check')
4. Repeat #2 and #3 three times.
5. Pick the best one and do it.
6. Keep doing this until you're really fast at thinking of good openers/routines.
At first you'll be slow. You'll think of it an hour later but the more you do it, the better you get at it.
If a person can do the Three Choice Technique enough, you won't need a guru because you'll be one.

p.s. This is my technique. I can't copyright it or trademark it. This is GOLD but I've only shared it with close friends and allies. Put it to good use.
