I was reading one of these books by Chogyam Trungpa and he wrote something to the effect of, "When you ask some one for advice see how often you genuinely don't know the answer and how often you're only asking for reassurance."

You can't prevent yourself from fucking up now and then, but the closer attention you pay to what's in front of you, the quicker you learn. Everything told to you here is just an extra layer between you and the situation of that girl in front of you. Be prepared to disregard all rules and everything you hear in /r/seduction if you have a strong feeling telling you otherwise. The details really don't matter as much as you think they do - it's all about attitude and the willingness to try until you are hurt and then go out and do it again.
