They don't see an instant result and decide it does not work.
Well, put it this way:
What does it take to learn to play music?
You don't just read a manual on playing piano, try for an hour, don't get the results you expected and give up, right?
Connecting with women in an effective way requires the same type of focus.
In my experience, it goes much faster though.
As I said, 1 to 3 months
You are now 1 week into it
Why does it is usually not instant?
Because it takes skills and practice to get it right, like anything else.
The key is not to give up when you hit a hurddle
You are on the right track!
