Just remembering something my wife said to me years back.
“Your problem is that you’re too smart.”
She’s right. Sometimes when you’re too smart, you seek out solutions to problems that are way more complex than they need to be.
And if anything, often times the best ways to create something complex is by building it or cultivating it slowly and simply over time, one step at a time.
In this way, the complexity you need arises naturally, with very little effort, as an emergent outcome.
