How hard is it to prove to guys that ... Their time is a priori MORE IMPORTANT than the girl's time.

Yes, in terms of "equality" it is not, and your time is equally important (and it is). But from the point of view of seduction, you need to have an advantage in your direction. We are always drawn to those who seem inaccessible to us and for whom we seem to be "a little short of it." That's why you need to put yourself a little higher than the girl - your business is a priority. Of course, this position will pay dividends only at the beginning - if you want to enter into a relationship, you need to change the “mode” to parity. But you don’t even reach the point of running after a girl for several months. This is extreme.
