Somewhat recent social media trend of "how I start my day as a 19 year old millionaire tech-entrepreneur homeowner" (replace after 'as' with arbitrary garbage) where people pretend to social media that they wake up every day at 3 am to lift, run, meditate and prepare gourmet breakfasts in order to get an optimal start to the day. Most definitely a meme.
People in general thinking it is productive to to wake up early for no other reason than waking up early to be productive is also a meme.
