Core Concepts - The human brain is vulnerable in time perception [7] - Time perception is subjective and varies depending on the situation, such as boredom or love [8][9][10][11] - Love involves a cocktail of chemicals in the brain, including dopamine, norepinephrine, phenylethylamine, oxytocin, and vasopressin [12][13][14] Relationship Dynamics - A significant portion of marriages fail, and even among those that don't, happiness is not guaranteed [6] - Dysfunctional arguments often revolve around the same unresolved issues [16] - People learn how to argue from others who may not have healthy communication skills [17] - Healthy arguing involves addressing the problem together rather than as adversaries [19] Human Connection - Common problems in human relationships include choosing partners based on potential rather than reality, arguing poorly, and neglecting relationship cultivation [19] - Love alone is insufficient; maintaining a sense of immortality requires mutual care and a secure, predictable space [20][21]
