I'm not into fashion at all but, being in France, I do get to see quite a bit of it nonetheless and I tend to agree jaykilgore's comment. There is more creativity in fashion than in most other photography and therefore more freedom for the photog. But you need to be where fashion is happening.
As a pole, aren't you allowed to work (and live) anywhere in the EU? If yes, get your ass over to Paris or Milan (or wherever things are happening in Italy today) and find yourself a job as an assistant. Although being an assistant is not like going to school, you will learn plenty if you pay attention and, not the least of it, you will make plenty of contacts and that is one of the most important thing in this business to get started.
Now, if you do not want to leave Poland, how about trying music. Music is as creative and crazy as fashion and it is not as centered on a few spots like fashion. Actually, I was in Eastern Europe not that long ago to shoot some bands for a friend so there is work your way. You just need to figure out where to go to get it.
Good luck to you. It is refreshing to see someone like you here and I would keep your name on file for a possible assistant position but I think you would find what I do mostly, pretty boring.
