Happiness requires some form of struggle. The positive is the side effect of your ability to handle the negative. You can only avoid negative experiences for so long before they come roaring back to life. At the core of all human behavior, our needs are more or less similar. Positive experience is easy to handle. It’s negative experience that we all, by definition, struggle with. Therefore, what we get out of life is not determined by the good feelings we desire, but by what bad feelings we’re willing and able to sustain to get us to those good feelings.
There are a lot of people want to start their own business or become financially independent. But you don’t end up a successful entrepreneur unless you find a way to appreciate the risk, the uncertainty, the repeated failures, and work insane hours on something you have no idea whether or not it will be successful. What determines your path to success isn’t “What do you want to enjoy?” The question is, “What pain do you want to sustain?” The quality of your life is not determined by the quality of your positive experiences, but the quality of your negative experiences. And to get good at dealing with negative experiences is to get good at dealing with life.
