I tried a canned opener on this african girl, but I messed up the order of some words so it made no sense at all, so I had to basically re-start from scratch lol
Needless to say, the delivery was also off since it should have been funny but at the end it looked pretty creepy, she asked me a few stupid questions like what do i do, where i am from and stuff but I simply had no inspiration to come up about anything, even a cold read...It's one of those moments that basically all the theory you have in your head is erased and you just act in a incoherent way...like I knew perfectly I should not enter the interview mode and answer directly to questions "what do i do" and stuff...In fact I used the same stuff yesterday night in a club and acted correctly when facing the same question (i.e. I gave a light joke reply, mysterious or whatever) but in this case it was like I am a completely different person, i.e. like I was giving interview-style answer by instict...
I also *forgot* to use any time constraints, time bridging, I was just focused on pushing hard to get a number and close, like when she said "I don't know, I'm quite busy..." I replied "I have a lot of free time..." I mean does that make any sense what I have lol?
In the end she gave me the number even before I knew her name, but I bet it's going to be a huge flake.
I mean whole this thing with a daygame...it's so kind of unnatural...especially if you don't use softeners like "This might sound weird but..." etc. But IN SOME CASES I just forget everything and act completely differently...
Few days ago for instance I was able to do a much better daygame approach...Might be one of those days when I feel *strange*, don't quite like my new haircut or just the first approach did not go pretty well (the girl walked off immediately...)

But anyway sometimes there are moments that I just feel all the informations I have are contradicting and do not make any sense, that I don't know what is the best way to act, what to say, who to be, how to appear...

I really wanted to find a hammer somewhere and hit my head with it lol for srewing up the conversation...
I mean, everything should be simpler and more spontaneous, I mean why it can't be like just "I like you and I want to take you out, ok?" but needs a complex structure, attraction builders etc.
I used to get numbers also with that line alone (i.e. a honest line, since I don't give a shit about talking and getting to know a stranger in the middle of the street...only if she becomes invested and comes with me for instance to a bar/party, then I would be willing to get to know a little about her...before that I simply need force myself since I am not willing, I'm even not sure if I want her physically sto start with...) but all those are mostly flakes...

In my opinion, night game is much more productive, it's mostly dancing and enjoying the music and I never ever had flakes the next day given the fact that we had a makeout there a day before...Just the opposite, I had girls I don't really like chasing me on FB etc. and me not replying or replying with "empty content messages".
How to clear up the mind and get out of this mental mess/information overload?

Bro, you are over thinking the opener. The opener is just that... To open. The good thing is that you ARE OPENING. Learning how to calibrate her responses and build attraction and comfort is how your game will develop. Keep opening and practicing calibrating and you will see improvement. Your opener really is not important. It is actually the LEAST important part of pick up. I've never had a girl in my bed tell me "Well, your opener was a bit too situational and I felt as if it was canned, so have a good night. Nice meeting you!"

Keep up what you are doing. Dancing with girls is NOT game.

Why don't you try being direct an honest about the reason you are talking to her. Maybe that way you don't have to memorize a book.
