What is oh que sera?

"Oh Que Sera" commonly refers to the phrase "que sera, sera," which is Spanish for "what will be, will be." It became popular thanks to the song "Que Sera, Sera (Whatever Will Be, Will Be)" written by Jay Livingston and Ray Evans. The song was first introduced in Alfred Hitchcock's 1956 film "The Man Who Knew Too Much," performed by Doris Day. It became one of her signature songs and has been covered by numerous artists over the years.

The phrase embodies an attitude of accepting uncertainty and the unpredictability of the future. It suggests a focus on living in the present and relinquishing control over what cannot be foreseen or altered. This concept has been embraced in various cultural contexts as an expression of serenity and acceptance.
