Life isn't like this and no one's emotions are this pure and uncompromised. We're much more mixed, troubled, uncertain of ourselves. Real love isn't this self-sacrificing and unconditioned. It is mixed with unloving feelings like selfishness and pettiness and the desire for appreciation. Real suffering, sacrifices, and loss is not unconditioned and absolute, but laced with anger and resentment and self-justification.
Real virtue is often critical and intolerant of others' deficiencies.
And we lapse from virtue as often as we adhere to it. We lie to ourselves constantly with self-justifying stories about how much harder we work, how much more we deserve success than others do. One might say that the very appeal of Hollywood film is proof of our emotional imperfection. The only reason we crave these movies is because we are addicted to glamorizing our emotional states, to deluding ourselves, to telling ourselves comforting stories about ourselves. Their repressions are proof of our insecurity and desperation for flattery.
