Best of luck to you! If it helps, believe me, the ONLY way to get good at it is experience and listening to other people's work. Research, research, research. Then trial and error some mixes. Experiment. Even after you've finished a mix, if you're not on a deadline, play with the mix for fun. EQ some 250Hz under your snare drum and just see/feel what it does for you. Push an electric guitar through the S-Type console emulation with lots of drive. See how it works with the Tube Drive way up. Just see what happens. On a vocal, if you can get your hands on the Waves CLA-76 Blue or Black-face 76-Type compressor, hit the ALL button and see how this affects your lead guitar or lead vocal.
Just have fun with it. For fun, I'll tweak the "bump" of a kick drum last. There's a certain way I want to "feel" it in my masters, and I want it to be punchy, but not so much it draws attention to itself. Get good at that.
When you've made lots of changes and lots of tweaks, win or lose, your ears will better get to know your monitors. You'll begin to
expect how others will sound. When you get there, you're well on your way of translation success in the real world. That's my experience all the way!
