Happiness requires Choice: the world in itself is a neutral flux of “booming blooming confusion,” hence it is entirely up to us whether to view it as positive, negative, or as absent of all meaning.
Happiness requires Active Risk-taking: happiness is not produced merely by thinking or by resigning oneself to life’s circumstances, but rather by taking bold risks and acting on possibilities that come from the “heart’s center,” the Real Self within.
Happiness involves “As-if” thinking: while we cannot prove rationally that freewill exists or that life is meaningful, acting “as if” we are free or “as if” there is an ultimate meaning in life will through that very activity produce a free and meaningful life.
Happiness often comes after a Crisis of Meaning: throughout history, the happiest people often record going through a deep depression caused by a sense of the loss of meaning…these events should not be repudiated but welcomed since only through them is the “Twice-born” sense of renewal possible.
