I've seen so many young guys on a promising path of RP success shoot themselves in the foot by jumping the gun on bars and clubs. They fixate on it for some reason. If you are under 24 and look young, it is highly unlikely that you will see much success in picking up women in bars. These young guys are generally unfamiliar with the bar scene to begin with, they walk in there alone and super nervous, and they subsequently can't work up the nerve to talk to anyone. Not to mention a lack of sexual experience that makes a ONS very difficult for the man to pull off even if a woman was interested. This is a not a helpful exercise and only serves to push men back into beta-game. You have a hit a certain level of physical maturity and psychological fortitude before women in those contexts will immediately be interested in you. If you're under 24, you're hardly even a fully fledged adult and are finding a career and you're not a high value man (yet) by definition. You need to look and act a certain part and have a certain level of sexual experience where you may not be at this point to get consistent results out of the bar or club scene.
All you young guys out there, do yourself a favor and avoid starting out in clubs/bars. Go to large parties, go to college bars or places where the women will be receptive to you, try day approaches, and don't feel the pressure to need to close that same night. When you are just starting out, it is unlikely that you will be able to sleep with a woman on the same night as meeting her. Not that you shouldn't develop the skills but start off with something more manageable and work your way up. Remember that plenty of men have highly successful sex lives without ever picking up a total stranger at a bar and sleeping with her that same night. They just ask women to get a drink later and close that way. You should be focused on having some sex first, then worrying about ONS.
Remember that no where in plate theory does it mention anything about having to pick up women in bars. Or even ONS for that matter. It is only about having multiple options at all times and maintaining non-exclusivity. Focus on that. Don't walk into a bar with an air of horny desperation, every woman there will smell it on you. Ironically, I'm telling you to tone down your RP and just date multiple women normally. Even if its "slow" at first, it will build you up. RP has never been solely about ONS, so take my advice and don't start there.
