The correct answer to “how long?” is: Combined, total time: 10 minutes of effort over 8 hours of passive waiting. That’s a 1:48 ratio of work to reward, which is better than your love life, your job, and that Netflix series you paused six months ago.
So stir your oats. Cover the jar. Go binge-watch a show, walk your cat, or write a strongly worded email. Wake up, grab the jar, and pretend you’re a meal-prepping god. You have 10 minutes to enjoy breakfast, and you spent two making it. The other eight were just the universe handling your problems.
Now go forth and soak. Your future, well-fed self is already thanking you.
