Your undeveloped side is the fruitful one.

What it means

Your strengths are already used up in a sense: they are what you do every day. Growth lies in the parts you have neglected. That is why later life so often asks you to develop what you avoided.

The source

"Your undeveloped side is the fruitful one." Carl Jung said it in Contributions to Analytical Psychology (1928), 'Psychological Types' (lecture, 1923). Translated by H. G. and C. F. Baynes, 1928.

"Thus the undeveloped functions are always the fruitful ones, and so it is no wonder that in the course of life the necessity increases for a completion and transformation of the conscious attitude."

Who said it

Carl Jung (1875–1961). Swiss psychiatrist who broke with Freud and founded analytical psychology. He mapped the persona, the shadow, the collective unconscious and the lifelong work of becoming yourself, which he called individuation. Our lines come only from his writings published before 1931, in our own translations from the German or in English translations of the time.
