My 3rd Game on this Site

Hmm sure I guess. Someone else suggested the King's Indian but I don't want to throw myself around openings a lot but focus on one specifically. I guess I just should stick to 1. e4 though I dislike it =/ heheh

As an example of how "developing on principle" is incorporated into an opening system, take a look at white's development in the following, arising from a Queen's Gambit Declined. Note how pawns occupy and/or bear on center squares. The knights also exert control on the center. The king knight supports the dark squared (queen's) bishop. The queen's bishop, often stuck behind pawns in queen pawn openings, is out in front of the pawns and active. The light squared bishop, which can pass through the f2-d4 pawn chain is well posted, and white has castled. All this in eight solid moves.

The Queen's Gambit is so solid, it has given rise to a huge number of defenses, and it all gets rather complicated. Low rated black players have fits playing against it, though as is true of ALL openings, you can't just memorize a move list and play it in all situations.

On a side note, you mentioned the recommendation for the King's Indian Attack. This essentially is white playing a defensive system, the King's Indian Defense (KID), a half-move earlier than if he were black. (The English is often thought of as a Sicilian Defense by white.) The KID was designed to counter or circumvent the Queen's Gambit.

Whatever you choose, play what you enjoy. If that's the English, so be it. I just didn't want to be recommending it. Look at a lot of systems, but don't expect to learn them all. See what appeals to you and what you think you can learn and understand. At least look at the Queen's Gambit, because you're likely to have to face it sometimes, anyway. Look at the Torre Attack. That can be fun to play.

Hmm, alright, I'll read on both of them. :) I just want to have a more original move than 1. e4 to play every single game. A little variety to keep interest :) The 8 move example you showed me makes lots of sense, and indeed I do try to prepare my opening game in a similar mindset. I'm getting better at it, I think. But I do have a question about that opening. I think I know it's ill-advised to accept the Queen's Gambit as black, but what if you do? You are slower in development but it's so early in the game can white really capitalize on that? Like, idk.

btw, would you like to add friends and challenge to a game? :)

The Queen's Gambit Accepted is playable, as long as black doesn't try too hard to hang on to the extra pawn. That's why some people say the Queen's Gambit isn't a true "gambit." As with everything, there are plusses and minuses for both sides.  If you play the QG as white, expect some people to accept. If you choose to look into it, look at QGA and QGD lines.
