zayuuh, I have a few points for you:
A dream that I must fulfill, every day here working and everything, it feels like it's lashing onto me, no way out of it.
My first bit of advice would be to remove the stronger emotions. Passion for aviation is certainly a key to success in many parts of the world. Without it, it is hard to grind through the lower stages of your learning and career. But your passion can be preyed upon, and not always by others. Many pilots have been given promises of a future, only to find their money was taken from them from a flight school manager or an instructor who was more interested in you giving them money than them giving you instruction. In the same breath almost every flight instructor has had that one student whose passion exceeded their ability, and that student wasted tens of thousands of dollars bouncing between instructors, each of whom tried (and failed) to get the student to realize flying wasn't for them.
I'm not saying don't enjoy your training or take pride in the accomplishment once you're done, not at all. I'm saying you need to temper your feelings when you are looking for a flight school and certainly more so while you are undergoing instruction if you want to breed success. Your stronger emotions will blind you to the reality of the school or your own performance. Take your statement that an FAA or other licenses are crazy expensive as an example. That's apparently your whole rationale for discounting them. But have you stopped to ask yourself why certain licenses or flight schools are more expensive than others? Could they be more globally recognized? Might they present you more opportunities sooner than others? Might they be easier to convert later on should you need to move and obtain a new license? There is a saying: you have to spend money to make money. Doing something as cheaply as possible can lead to just as poor and costly an outcome as going the most expensive route. Price is both the most important and least important aspect of your flight training. Least important because at the end of the day, we all walk out with the same thing in hand: a license to pilot an aircraft. Most important because other than a house, this is likely the most costly investment you'll ever make, and it will take up to a decade to see any return on investment.
what I should aim for
My second bit of advice starts off with a statement: Only you can answer what you want from this industry. Is this a passion project where you want to fly on the weekends or do you want to make this a career?
You write as though you want this to be a career, but there are so many different options within the term "career" that your aim will fall short if you don't have a clearly defined end-target. This end-target (or goal) will outline everything else you do. Your end-goal will also allow you to set up your other goal: short, medium, and long term. You are working on a short term goal of picking a flight school cannot be successful without that long term goal. So you have to work backwards. Where do you want to be in 5 years? Once you've clearly defined that, then you can ask what steps are required.
But a word to the wise: once you've picked your long-term goal don't lose sight of it, but don't also focus so much on it that you lose sight of what's of immediate importance. I say this from the experience of a few students who wanted to be airline pilots. They wanted it so bad they dressed, acted, and pretended to be airline pilots while at the flight school. It would have been funny if it wasn't so sad given their performance. They could tell me everything about an a 747, yet they could not consistently make proper radio calls in the circuit or land within the touchdown zone. They couldn't do this because they spent all their time focused on the far future, not the next lesson.
