How many approaches do you actually do a night?

Mystery suggests that newbies do 4 approaches an hour for 4 hours. 4 sets x 4 hours doesn't seem like a lot when you read it in a book, but I find it's tough to do in real life at my current level, especially when I'm an introvert and often need recharge time between sets. Currently I'm doing about 8 approaches a night (over maybe 4-6 hours). I'm still a beginner, so I'm hoping that will go up, but I'm curious, how many approaches do you guys realistically do a night?

(Sometimes I feel like doing too many more approaches gets into that pathetic territory where I'm just walking up to every girl in the bar, but that probably shows that my inner game needs work!)
