You may be familiar with the idiom "A shot in the dark." My life on the whole feels this way right now because of recent events, namely, the loss of a job that was my primary source for income. Anyhow, I plugged this well known phrase into Google's TextFX AI text generator and got back the following similes:

"I felt like a lone ship sailing into uncharted waters, with only a flickering compass to guide me."
"The future was a blank canvas, waiting for the bold strokes of chance."
"It was a gamble, a leap of faith, like a tightrope walker crossing a chasm with no net."
"The silence afterwards was deafening, like the hush that falls after a storm."
"I felt as fragile as a soap bubble, knowing it could burst at any moment."
"The odds were stacked against me, like a house of cards precariously balanced on a gust of wind."
"It was like trying to paint a portrait in the fog, hoping the brushstrokes would coalesce."
"My heart thumped like a hummingbird's wings against a window pane."
"I felt as blind as a bat in a moonless night, yet somehow compelled to swing."
"The answer was out there, somewhere, like a lost key in a field of wildflowers."
"It felt like throwing a pebble into a bottomless well, hoping for an echo."
