great advice !
often we get caught up in that visual aspect... (making sure that we are not making that little red light that says ¨clip¨ go off!)
listening is much much more important and sometimes a thing i struggle with.
i can only add that making sure you have the most accurate reference possible WILL help your mixes! some guys like head phones, some guys like monitors. i happen to be a monitor guy. i need 3 more sets!!!
