Analysis kills spontaneity. The grain once ground into flour springs and germinates no more.
— Henri Frederic Amiel

Through spontaneity we are re-formed into ourselves. It creates an explosion that for the moment frees us from handed-down frames of reference, memory choked with old facts and information and undigested theories and techniques of other people's findings. spontaneity is the moment of personal freedom when we are faced with reality, and see it, explore it and act accordingly. In this reality the bits and pieces of ourselves function as an organic whole. It is the time of discovery, of experiencing, of creative expression.
Viola Spolin spontaneity quote

America is neither free nor brave, but a land of tight, iron-clanking little wills, everybody trying to put it over everybody else, and a land of men absolutely devoid of the real courage of trust, trust in life's sacred spontaneity. They can't trust life until they can control it.
— D. H. Lawrence

Winning children (who appear so guileless) are children who have discovered how effective charm and modesty and a delicately calculated spontaneity are in winning what they want.
— Thornton Wilder

Psychobabble is... a set of repetitive verbal formalities that kills off the very spontaneity, candor, and understanding it pretends to promote. It's an idiom that reduces psychological insight to a collection of standardized observations, that provides a frozen lexicon to deal with an infinite variety of problems.
— spontaneity quotation by Richard D. Rosen
