When skillful, equanimity is not a generalized indifference to everything. Instead, it’s meant to focus your efforts on areas that will pay off in terms of a much higher and truly satisfying happiness.
"Two points about limitless equanimity: 1) When skillful, it’s not a generalized indifference to everything. Instead, it’s meant to focus your efforts on areas that will pay off in terms of true happiness. 2) It’s not the goal. Instead, it’s a useful emotion to develop on the way to something much higher and more satisfying." ~ Thanissaro Bhikkhu "Meditation in Practice"
