I like routines, but there are several problems and advantages to them, alot of guys turn not using routines into some sort of ego trip ''I don't use routines cause I'm better then that, I just pull left and right on personality alone''
chances are all those guys are using routines and just don't realize it, they just say HURR DURR I'm too ALPHA MALE to use routines, because they don't practise mystery method like a religion (MM is simply mystery's routine), how ever they are doing and saying the same shit every time to every girl with the exception of a few contingencies and calibrations according to how the interaction goes, and have formed their own routine (rather then using mystery's routine, aka MM)
straight from the dictionary
Quote:
Routine [roo-teen]
1.a customary or regular course of procedure.
2. commonplace tasks, chores, or duties as must be done regularly or at specified intervals; typical or everyday activity: the routine of an office.
3. regular, unvarying, habitual, unimaginative, or rote procedure.
4. an unvarying and constantly repeated formula, as of speech or action; convenient or predictable response: Don't give me that brotherly-love routine!
5. Computers .
a. a complete set of coded instructions directing a computer to perform a series of operations.
b. a series of operations performed by the computer
to be honest, having 5 hours worth of script from another person's routine, is not the same thing as just using a few of other people's routines combined with your own routines and sprinkling them into your sets to ignight some emotions and get around tests and problem areas (lmr anyone?

), if you absolutely have assburgers and have absolutely 0/100 social intelligence, then having 5 hours worth of material would be nessicary for you to have a chance, but obviously your interactions would seem fake and contrived until you could act them out flawlessly and even then you would have to find the right kind of girls to fall for it, especially if you had to stick to your script no matter what happened constantly trying to cut threads and re-thread back to your exact outline of conversations and routine stacks in order, on the other hand, having absolutely no plan in mind, with no ''regular things you say or do'' can make things boring, if you are in a bad mood or your brain is not functioning at that higher level, then it will be extremely difficult for you to pull random charisma out of your ass, this is not to say that some guys can't do this but if you are telling stories, or saying the same shit or recycling jokes, you are using routines
and honestly, having a good amount of routines to fill gaps and make the conversations you have interesting is a nice to add into your game, but alot of guys will take that too far and just stack routine after routine, until they are just trying way too hard and it is apparent that they are over compensating for approval, ''overgaming''
another problem with routines is some guys turn into approval junkies, they develope some good routines that get really good responses, then feed their ego's with external validation, this can lead you to feel like it is never enough, the girl is sitting there laughing and having fun and all the guy has to do is start escalating and ask her some questions about herself, but instead he throws out routine after routine looking for that approval, the magic moment when he just has so much approval from the girl that she just drops to her knees crying with happiness ''OH PUA, YOU ARE SO FUCKING HOT AND CHARMING, PLEASE LET ME SUCK YOUR COCK FOR THE NEXT 20 HOURS STRAIGHT!!'', but the thing is, you will never neg or dhv a girl into sucking your cock, if she randomly initiates it, she was most likely planning to do it even if you were significantly more boring to talk with, if the girl is in a good mood, you have what you need to start connecting and escalating, you don't need her approval, instead just know that you are entitled to that pussy, just simply because you have a dick, and she has a vagina, and dicks go into vaginas and that is the way we are made, naturally, she wants a dick in her vagina, when she is seeking your approval (actually pay attention to when she is trying to impress you, rather then spending all your time trying to impress her), give your approval and attention to her little by little the more she works for it and go easy on ''overgaming'', it is like discovering a new area, assume she has interested you, but you are not sure and want to figure out if she is cool, this is the art of getting someone to look up to you, and all you have to do is be more confident and secure then them and offer them validation little by little as they seek it, without seeking their validation, once a person thinks you are valueable in a social sense, you will get investment, the more you let the person invest for you, the more of a connection you will form together, and the more the person looks up to you, the easier it will be to get that investment
either way it is a matter of choice, it is rare to meet a guy who can always be charismatic and on point confident 100% of the time without repeating things he has done in the past, we are simply creatures of habit, and shaping new habits and getting rid of old ones is what self improvement (and pickup) are all about
