as simple as these tips are, they will sure help, at least I was very surprised how effective they are and how I underestimated their effect.
These are usual suspects at least for me: kick, bass, snare, vocals, any other main/lead instrument
and finally, a mix of the two, where you find out the volume range where you can mix something
Try to see broad eq bands as volume faders too, EQ is basically a 'multi-band' volume control
