If an action leads to pain, it is corrected. If an action that gives bad results is relatively painless, it is ignored.
Even though we recognise that our habits will lead to a decline into ill-health, despondency, or disease, since the process is so gradual, and the deadly payoff so long deferred, we see no reason to change them even though we may want to.
A mind that constantly seeks pleasure inevitably finds its shadow, pain. They cannot be separated.
Consciousness requires both pain and pleasure to sustain itself and to thrive. To strive for pleasure to the exclusion of pain is in effect to clip the wings of consciousness itself. So the more we struggle for a life of pleasure, the more we are killing what we love.
