Yes u do, brother!
Very basic rule for successful pick up- never get stupid drunk. Actually, never get more drunk than the girl u r hitting on is.
When u r drunk u think u cool and whatever, u all over the place. The false confidence that alcohol gives will make u look like a fool in the eyes of the women.
Ok here's what a night out should be form my experience.
1. Get your plan going on- where are you going, how many friends etc (avoid big male companies- chicks DO NOT like them- they are loud and drunk. Most the times in the eyes of women we look like bunch of apes riding a testosterone waves, acting like dicks and whatnot. Get with a friend or a couple of friends who have same interest as u do- avoid going out with guys who'll get stupid drunk and u'll have to take care of or watch out for them so they do not get into fights instead of focusing on women.
2.After u have already figured out who u r going out with and where, get showered, get dressed, put on your best looks. Not everyone is handsome but if u make an effort girls are def gonna take notice and u will improve your chances the least
3. Get with your buddies for some pre drinks or whatever eases u up. Get in a mood but dont get wasted- dont make the friends thing the accent of the night, so dont take too long either.
4. Chose a club to your liking. I cannot help a lot here since we all live in different towns/states so yeah, u have to do your homework there.
5. The moment u get into the club starts the tricky part. VERY IMPORTANT: u have to know and have to accept the fact that u're inevitably going to get turned down, dont let that disappoint u or make u quit. Dont make it a self esteem/confidence issue, cause its part of the game. Your not doing anything shameful or weird. U are hitting on women, thats what men are supposed to do! Seriously, look at it this way: out of all the chick in the club some will not be attracted to u, some will be with their boyfriends, some will be out on one of those "girls' nights out" where they have gone out to dance and have fun and not care about men. The chicks that are going to be available to you and DTF are gonna be a really small percent of the women in the club. This is why when u enter u must check out whats what. U have to recognize the abovementioned categories of women and simply not make moves where u figure u gonna get turned down. U must also mind the competition, not to wait too long cause someone else may pull the trigger before u and steal the prize.
In order to be able to be good at that u must understand women psychology. U must know that there zillion things that can end up screwing your chances and mind them. Women are like game and we;re hunters. Club is the hunting ground you chose. Women are gonna be suspicious, they are gonna be crazy, bitchy and cold unless u act right.
6. So yeah, when u get in the club scope the perimeter. When u choose a target dont get like straight there, dont hurry it, but dont stand around doing nothing either-chicks will never get to u themselves, not in a club., So wait for an appropriate moment and create a situation instead. An eye contact, a smile or whatever, prepare them for yourself let your presence be known. Remember they are a game- the approach is everything- so if u pop out of nowhere u most likely gonna scare them away.
7. Ok lets say u have prepared the ground for an action. Go and meet her (she'll most likely be part of some group of girls- smile to all, let out a positive vibe). Be yourself. I know this is like cliche but it works. From here it would either work out on itself or not...depends on u and your confidence- u must be confident, not cocky but confident, women will never pay attention to a guy with no confidence, especially at a club.
8. If she turns u down dont get discouraged. Dont try to hit on some of her friends either. A woman will very rarely pay attention to someone her girlfriend has rejected! (even though I have done it- girls were pretty drunk

) But yeah sreiously dont go down that road. Remeber this is all something normal, she wasnt down, someone else def is, u just need to find her. So leave with dignity, dont look desperate.
9. Go back to your buddies, chill, dont look desperate. Take the time dance a bit, have fun- thats what its all about.
10. Then chose another target. Possibly at other part of the club where your rejection has remained unnoticed (women do not like guys who'll go to every girl in a club and try and hit on them. The key to women is to make them feel special. She cannot feel special if she watches u hit on other women, then get turned down and then go to them. It will not happen, even with the slutty ones).
10. Make a move to the next one. Its the same drill- make yourself noticed first, make sure u get the right signals from the girl too. Go to her and bring your best game!
I'm tired of typing. Hope what I wrote makes sense and help u out
