The best advice I always try to give in situations of dumbing is “Stop trying so hard.”
Let it come naturally. Don’t fixate and focus on whether you are doing dumbing right.
Just do it.
Stop thinking so hard.
Stupid is as stupid does.
Focus on your actions and just allow the programming to do its work.
The unexamined life is the only one worth living.
After 3 months you’ll look back and see all the times when you were 100% living that dumb life. In 6 months, you’ll realized that it’s started to be your dominant mode of being. Not thinking so hard about bullshit. In a year, you won’t even be capable of that introspection.
