I know about that business personality/private personality dichotomy. Amazing how much discrepancy there is and it's all in the same person!
So you've developed a confident, take-charge "I know this" personality while at work but don't have that in the club? Somehow you need to build up the civilian side (so to speak) to match the business side.
With most things, start small and in controlled situations, get a lot of reps in, and slowly escalate (got this from Steele, btw..)
Only you know where your weak points are. Is it in approaching women above a 6 rating or above an 8 rating? Is it making conversation with anyone without handling business for them? Or can you handle most of that but find it hard to approach women in a club setting where they are at the top of their game with bytch shields on full and laser tongues set for full laceration?
Pick what you want to improve and start comfortable, get in a lot of practice reps and begin to escalate the challenge. Work up the ladder (my guess is you're probably several rungs up the ladder already and can begin work from the middle....)
For example:
Talking with people.
--1st rung: engage everyone you meet in a normal situation (clerks, people at a bus stop, people asking for directions...) with a single comment. Engage anyone and everyone regardless of gender or age. Just make a comment.
--2nd rung: escalate---make sure you have a simple, non-DJ comment or conversation with a clerk you find somewhat attractive.
--3rd rung: escalate--same as #2 but do it with an attractive one...
Move up to the next floor: respond to or initiate a comment or conversation with someone who isn't engaged in an everyday--just make any dumb@ss comment with anyone of any age or gender.
---next rung: do it with a female who you are not attracted to.
---next rung: do it with a female who you find "not bad".
---etc.
KEY: after each encounter, go over the encounter and replay it in your mind. Ask:
--what happened?
--what did I wish happened?
--how would I do it differently?
This is best done if you do it in 3 columns and WRITE it out. This absolutely drills it into your subconscios and stops all the mental mind-fvcking you do to yourself when you don't do as well as you intended.
It's a lot of work but unearths pure gold.
Pretty soon (weeks? months?) you're in a club practicing and using this learned behavior.
