This is actually a good advice. I realized I myself follow it naturally. Like for example I never watched the Boruto movie or followed DB Super and One Piece. Because I felt annoyed by some of the stuff they had on there. It saved me the trouble from feeling disappointment because I ended up watching stuff that actually interested me.What I say often enough is that- people shouldn't be forcing themselves to read a story they have lost interest in to. It only makes you dissatisfied and with time the feeling of annoyance will only increase. Because you are not doing because you want it but because you think you have a right to read it, annoy yourself and then rant over it. ( you do have the right but it's nothing positive about it)
