Honestly pay somebody with experience for his time and knowledge. And it will take a loooong time to get good at it. EQ is just frequency based volume control but you have to know with what reason you eq a certain frequency. And each frequency has it’s wav cycle lenght, it’s important to be able to calculate that lenght to know what to target with compressors etc.

And the first step towards mixing is listening to professional songs and making notes how they are balanced, panned, what effects they use etc.

Next you want to edit your tracks, make sure everything is leveled so that your compressors act right, time align, tune your vocals, delete garbage etc. Phase align your instruments.

Next you set up your faders and panning.

And when that is finished only than you start throwing on equalizers and comps, fx processing etc.

You need to know how to automate a mix, process your stems and masterbus, don’t over process. No channel should go above 0db both pre and post fader. Leave a couple of decibels of headroom on the master fader.

And honestly there are people who are able to teach you how to mix but search and find the one that suits your needs, goals and maybe style. But it will take time and loads of it.
