Hi Russian speakers, can any of you give me an acurate or similar translation for this phrase:

"Whatever floats your boat" or something you might use to express this definition:

A term used to say, "I'm glad that makes you happy, even though I don't get it myself."

This is a phrase that often means whatever "soothes your soul" or whatever "works best" Aka- Whatever you feel like doing.
