I with Jaz here once a week is SO not enough!.... Once a day is acceptable and will get you up to an average
PUA's game in 30-60 days but you gotta get out there daily take every opportunity to practice.
I practice everyday although all of this is not sarging for the outcome of getting a HB wet. Sometimes I do it just because the person looks a little down or preoccupied they may not even be above a 5 and I think "ah ha an unprecedented opportunity to practice and make someone feel good at the same time!"
I practice at work in meetings, with colleagues and when I need to convince people to do things my way... I still consider this sarging, just not for the same outcome that I want when out on the prowl for new untapped HB booty.
