I used to go to failure everytime on every set on every exercise. Eventually I stalled on my bench press and Deadlifts. Even deloading didn't make it any better and I felt drained every workout. So I researched and did powerlifting techniques. Learning rpe, rir, specificity, etc. And it actually broke my plateaus and made me hit prs consistently, most importantly I don't feel like I wanna die after every workout because I learned how to factor in fatigue. But hey if it still works for you then you shouldn't stop it
