The total amount of suffering per year in the natural world is beyond all decent contemplation.
The molecules that mediate pain are ancient, revealing how deeply rooted this sensation is in evolution.
Life is too short to wake up with regrets. So love the people who treat you right, forget about the ones who don’t, and believe that everything happens for a reason. If you get a chance, take it. If it changes your life, let it. Nobody said life would be easy, they just promised it would be worth it.
