No offense to some of you guys, but these rigid 4-7 days rules or whatever make you sound like either 80-year olds or 8-year olds.
I get that this was a good rule of thumb some 20-30 years ago, but in 2019 it's ridiculous.
As
BJP1991 said, "Waiting on purpose/for no reason is putting too much tome and effort into it."
And again: "Nobody is so busy they cannot send a simple text message."
You are not fooling anyone. They know you're playing games. And they will either lose interest or play games with you also. Maybe there's a small chance a desperate girl will hang to her phone all week waiting for a call. But quality women in 2019 don't have time for childish games. They have other guys interested in them. Just like you're pursuing girls with high IL, they will orbit towards guys with high IL.
Sorry for the long somehow offtopic post, but I really don't understand why some insist in following these kind of rigid rules blindly. Things change and we need to adapt! It's in our benefit.
Ontopic: BJP, keep up the good work! Don't fix it if it ain't broken.
Respect.
