Trust your own instinct. Your mistakes might as well be your own, instead of someone else's.
~Billy Wilder

Good instincts usually tell you what to do long before your head has figured it out.
~Michael Burke

Trust yourself. You know more than you think you do.
~Benjamin Spock, Baby and Child Care, 1977

Instinct is untaught ability.
~Bain

Instinct is intelligence incapable of self-consciousness.
~John Sterling

Trust your hunches. They're usually based on facts filed away just below the conscious level.
~Joyce Brothers

Intuition is a spiritual faculty and does not explain, but simply points the way.
~Florence Scovel Shinn

Reasoning at every step he treads,
Man yet mistakes his way,
Whilst meaner things, whom instinct leads,
Are rarely known to stray.

~William Cowper

The most decisive actions of our life... are most often unconsidered actions.
~André Gide, The Counterfeiters, 1926

A leader or a man of action in a crisis almost always acts subconsciously and then thinks of the reasons for his action.
~Jawaharlal Nehru

[T]he invisible intelligence that flows through everything in a purposeful fashion is also flowing through you.
~Wayne Dyer

I suspect we have internal senses. The mind's eye since Shakespeare's time has been proverbial; and we have also a mind's ear. To say nothing of dreams, one certainly can listen to one's own thoughts, and hear them, or believe that one hears them: the strongest argument adducible in favour of our hearing any thing.
~Augustus William Hare and Julius Charles Hare, Guesses at Truth, by Two Brothers, 1827

Instinct is the nose of the mind.
~Madame De Girardin

I would rather trust a woman's instinct than a man's reason.
~Stanley Baldwin
