Does anyone actually maintain a detailed monthly budget after reaching a comfortable income, or do you just automate savings and spend the rest?

The moment my paycheck hits, I deploy it straight into the market. I've never tracked expenses a day in my life, even when I first started working. Whatever is left over, I simply make work.

Once my income became comfortable, I stopped tracking every expense and just automated my savings and investments, then spent the rest without overthinking it.
