Viktor Frankl. Man’s Search for Meaning,
the real aim of human existence cannot be found in what is called self-actualization. Human existence is essentially self-transcendence rather than self-actualization. Self-actualization is not a possible aim at all; for the simple reason that the more a [person] would strive for it, the more [they] would miss it.
For only to the extent to which [people] commit [themselves] to the fulfillment of [their] life’s meaning, to this extent [they] also actualize [themselves.]
In other words, self-actualization cannot be attained if it is made an end in itself, but only as a side-effect of self-transcendence.
