Study one or study all?

Ii mean I'm new, I know very little but I've put quite a bit of learning into openings, mostly black. I've got the most caro lines, the dragon & some french but I'm not sure where else to go. Caro I just don't like after all variations; Sicilian I do like in most dragon formations (hyper accel-normal); french is still new and I'll never change my d4 defense. Aside from that I hate playing with white, I've tried london, english, catalan, ruy lines, none of them fit me. The only line I love is KIA vs French, suggestions? Think psuedo catalan is my best run white open

I think I'm gonna hard stick sicilian for now, maybe english/ reversed sicilian or KIA if some could help w/ that?

It sounds to me as you are focussing to much on the opening. Try just to se it as a way to get the game started. It is not in the opening you win or loose your games.

Jokes aside, I agree with @Toldsted. Just choose one opening and stick with it for a while until you understand the positions. You will lose for a while, but that is part of the process. Analyze your games afterwards and eventually you will like the positions.

Choose one variation in all openings. Not study all variations of all openings. Without my openings work I cannot be 2000 online. Shifting from opening to opening are for master tournaments so particular opponent preparation will become useless. Of course do not forget tactics, strategy, and endgames. Sounds too many that is why we love chess. 

Study all openings, but not too deeply. Simply learn some basic pawn structures that arise from [these] openings, and the basic plans for white is to [this] and for black he might want to do [this]. 

But if you're learning something like the Dragon... yeah that won't apply lol.

Okay; I like what Giant & Snu said. I think over doing variations was throwing me instead of also playing in the moment. Agree with Snu when it comes to recognition.

Yes. knowing plans for both sides allowed me to be more flexible and spend less time in the opening.

And I don't know any opening. (Exception for Kings Gambit. I couldn't stop myself from forgetting that ). But I know the opening principles and nowadays I am not trying to violate any of those and winning most of the games. Still, I am a noob player with a 650+ rating.

Re: Chess is 99% tactics. (Though I often do mistakes )

To echo what others have said I'd recommend just playing a lot of one opening as white and one opening against d4 or e4 as black many times to get familiar. As you play more games and fund success/shortfalls in the opening with what arises, you can expand your opening repertoire.
