There are still some people in my life (like my ESFJ sister) who I see no point in talking to when I'm about to snap at her, because I know it would be a wasted conversation. She deserves every ounce of my rage once I'm at that level lol.
It's not easier of harder, all it is is an awareness to work upon, a knowing that if I talk now I can prevent losing it towards someone I care about. It doesn't always happen, but I have moments in which I manage it. The moments I do manage it has been prompted by remembering that this is something I want to work on, remembering that it's an INFP weakness, and mentally talking myself through it with the remembrance mantra.
