You CAN simply use a sense (i.e. 'sight') as your prompt, but you can also use one of these quotes as your prompt/basis

SIGHT

"For my part I know nothing with any certainty, but the sight of the stars makes me dream." - Vincent Van Gogh

"I only hope that we don't lose sight of one thing." - Walt Disney

"The only thing worse than being blind is having sight but no vision." - Helen Keller

"Never lose sight of the fact that the most important yardstick of your success will be how you treat other people - your family, friends, and coworkers, and even strangers you meet along the way." - Barbara Bush

HEARING

"The most important thing in communication is hearing what isn't said." - Peter Drucker

"Fear is static that prevents me from hearing myself." - Samuel Butler

"I'm tired of hearing about money, money, money, money, money." - Shaquille ONeal

"After all those years as a woman hearing 'not thin enough, not pretty enough, not smart enough, not this enough, not that enough,' almost overnight I woke up one morning and thought, 'I'm enough.'" - Anna Quindlen

SCENT

“Money does not smell of the mire whence it came; it has the glorious scent of what will be.” - Catulle Mendès

“Nothing revives the past so completely as a smell that was once associated with it.” - Vladimir Nabokov

"God gave me some weird, beautiful scent that makes men and women go crazy. People compare it to Carvel. It is a whale of a smell." - Adam Sandler

"I think scent is sensual. I guess evoking a mood or a spirit is key, and I think with the women's fragrances we have evoked different types, moods or sensibilities of a woman - whether it's Daisy with the sweetness and the innocence or Lola which is more provocative, y and sultry." - Marc Jacobs

TOUCH

"At the touch of love everyone becomes a poet." - Plato

"Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around." - Leo Buscaglia

"Learn to get in touch with the silence within yourself, and know that everything in life has purpose." - Elisabeth Kubler-Ross

"One touch of nature makes the whole world kin." - William Shakespear

TASTE

"Cowards die many times before their deaths; the valiant never taste of death but once." - William Shakespeare

"A taste for truth at any cost is a passion which spares nothing." - Albert Camus

“So he tasted the deep pain that is reserved only for the strong, just as he had tasted for a little while the deep happiness.” - F. Scott Fitzgerald

“I'm hungry for a juicy life. I lean out my window at night and I can taste it out there, just waiting for me.” - Brigid Lowry

MULTIPLE SENSES

“Touch comes before sight, before speech. It is the first language and the last, and it always tells the truth.” - Margaret Atwood

“You must learn to heed your senses. Humans use but a tiny percentage of theirs. They barely look, they rarely listen, they never smell, and they think that they can only experience feelings through their skin. But they talk, oh, do they talk.” - Michael Scott

“All our knowledge begins with the senses, proceeds then to the understanding, and ends with reason. There is nothing higher than reason.” - Immanuel Kant

“Lose your mind and come to your senses.” - Frederick Salomon Perls
