Of course, Loqi’s suggestion could contingently be less optimal than the less easy to accept presentation.
While the approach you suggest could provide a more subjectively negative experience, the cognitive dissonance could cause the utterance to gain more attention with the brain as a more aberrant occurrence in its stimuli and as a result be worthy of further analysis and consideration.
I am generally in favor of delivering notions I believe to be helpful in a manner which can/will be accepted. In some cases however, others are able and more likely to accept a less than pleasant delivery mechanism. This is contingent upon the audience, of course, as well as the level of knowledge you have about your audience. In the absence of such knowledge, the more gentle approach seems advisable.
Regarding pieces of oneself, consider the ideas of IFS (internal family systems). “Parts” can be said to attenuate to different concerns and if one can distract from others then an opportunity to maximize utility across dimensions may be missed. One might also suggest that attenuation to only one concern over time can result in a slight movement towards disintegration as a result of increasingly strong feelings about “ignored” concerns. Integration or alignment, with every part joining a cooperative council is often considered a goal and personification can assist some in more peaceably achieving that. I personally found the suggestion to personify felt weird and false.
