“What doesn’t kill you makes you stronger.”
Happiness and suffering are two sides of the coin of chance. One where I get what I want and the other where I don’t: materially, mentally or emotionally. To actively seek happiness is to chase a chimera, because happiness is a side effect of fortunate events, not a destination.
Seeking constant happiness leads to a lack of appreciation of happy circumstance when they do occur, and is a slippery slope to self indulgent and self medicating behavior to maintain it. Likewise, to suffer and rail against fate is a waste of time and energy. If there are lessons to be learned from misfortune, I will learn them and move on with my life.
What life is, is struggle, from birth to death: to understand the world, myself, and the role I have within it. Like a caterpillar emerging from a chrysalis, the struggles and obstacles I go though in life are an essential part of growing and developing my mind, body and spirit. If I did not have these obstacles in my life I would not be where or who I am today, and would instead be softer, weaker and less prepared for misfortune.
Struggle is a given as long as I am alive, suffering because of it is optional.
