At your level, the great pleasure is that you can still improve by a lot, and fast. Whether you'll hit the bar at 9k, 6k or 1d, remains to be seen, but I am willing to wager you can improve 6 stones in the next six months or one year, probaly more and faster.
I am on the level of: "first corners, then edges, then the center". Which is valid advice for a beginner.
It's a valid advice, but it's an advice for the opening stage, which is not where you will win games. It is perfectly possible at 18 kyu to screw up a game starting from a decent opening.
However, it's not completely true anymore (or not all), when you play against advanced players.
Yes it still is, but against advanced players it is even more difficult to win a game, even if you played a good opening.
At that level, sometimes one should give up defending a corner, or go towards the center early on. You should play big, but not too big, look for influence, but not forget about territory. And there is no simple advice for that, apart from recognizing certain patterns. Which means study, study, study.
Rather, play, play, review, play.
I have tried, e.g,. the videos of Nick Sibicky on YouTube who is an excellent teacher, but if I try to play like that, I lose with 100 points of difference instead of 30

Which likely means you haven't progressed beyond very basic tactics and strategy (stay tuned) and likely make major errors that cost the game.
I have come as far as "don't defend too much and sometimes do something that seems hopeless or crazy or useless" (like cutting whenever you can), and - weirdly - enough, sometimes that works, but I still end up not knowing why really.
I would not "do something that seems hopeless". Like you say, if it works, you still don't know why. Rather "do something that seems to work". If it works, you were probably right and if it doesn't, you have learnt something.
Now for the real basics that will lift your game immediately:
1. strategy: connect/move out your own groups on a large scale and separate/surround the opponent's groups, as long as these groups are not clearly alive. Go is "the surrounding game".
2. tactics: always be aware of your liberties and the opponent's liberties; in local fight, try keeping the upper hand in liberties
3. mentality: use the time you have to consider at least one alternative move, and read out 3 moves for the move you're thinking of and the alternative(s); then decide which is better
I'm nowhere mentioning territory, influence, shape, sente ... because I consider these already second level concepts. In the early stages, territory will come from living through connectivity, influence will follow from surrounding the opponent, shape will follow from thinking about liberties and connectivity and you may take the initiative whenever your alternative to the local move is a tenuki and you like it better.
Most of all you won't lose games due to outrageous blunders because you will remain concentrated on the moves
Post your next game here, make your own pre-review of how well you did strategically, tactically and mentally. Chances are you won't even need us for a while. Oh yeah, and play people of your own strength to measure your success.
