Life's art

Something you tell people that you have spent a really long time on, maybe several years. Yet in reality, it is just something you worked on, when you were temporarily high on social media motivation.

it should never be used instead of "life's work" unless you intend to make fun of someone genuinely passionate.

"Oh man, this life's art of mine has really taken its toll on my social life, I haven't seen my family for so long..."
"Didn't you start that project, after watching Bob Ross for 3 weeks straight?"
