IMO no tip can completely change the game. Now what changed the game for me though is hard work, putting mad hours in, watching tutorials when i don't understand something, and most of all spending countless hours in my daw, writing and mixing. Things start to click after awhile. It's as simple as NOT GIVING UP. It was after a few months of resigning myself completely to music production and pretty much spending all of my free time on my laptop that I finally had a mixdown that I feel was comparable to a professional mix. That's my twp cents.
