How do you manifest an SP without obsessing over the 3D?

I’m curious how people here approach manifesting an SP without turning it into an all-day mental job. A lot of SP advice says not to react to the 3D and to stay loyal to the version of the relationship you want. I understand the idea, but I’ve also noticed how easy it is to turn that into constantly checking, affirming, wondering whether I’m “doing it right,” and basically thinking about the person even more. For those of you who’ve had a healthier experience with SP manifestation, what actually helped? Did you focus more on self-concept, visualization, affirmations, or simply decide what you wanted and get on with your life? I’m especially interested in how people stay consistent without becoming obsessive.
