I read everywhere, that rear-ported monitors shouldn't be placed up against the wall. I would have my monitors like 35cm (14inches) away from the wall (and they'd also be aimed at an angle, so the distance from the wall would be around 50cm (20inches), I don't know whether that counts).

 Could you please give me more insight on this topic?

That is why I am buying front ported monitors. But thanks for advice!

Also Yamaha HS5's could be an option

They are my first monitors, I have done everything on my headphones so far. Unfortunately, I cannot raise my budget The other possible choice is JBL-LSR305, but it has sub on the back. Is it really that bad to have it that way near the wall?

Oo, thats exactly what I need, thanks 

So, I got to the point, where I think I am not progressing at all. I mean my music has been doing pretty awesome, getting to all the promotion channels, and I am kinda proud of myself. But it feels like I am not progressing as much (although people tell me, that I am still getting technically better, but my sound design is lacking probably). So that makes me demotivated and I rarely open FL Studio nowdays. And I really feel shit, because I want to make music. I am thinking about trying the Pomodoro Technique, but does forcing yourself into music help? And I always  tell myself to watch some tutorials, but it's the motivation that stops me. (here is my soundcloud https://soundcloud.com/fadexmusic). What should I do?

Thats quite on point! I would put the snare in the first part of the drop more in the middle, and make it more full. Also the intro melody+sound, well the whole intro is pretty strange.
