The Cost of Tinkering
Why doing less, most of the time, beats the urge to constantly adjust.
Once you’re invested, your instinct screams to do something — check daily, tweak, buy a little here, sell a little there. Overtrading is this urge in action: making frequent changes that feel productive but quietly erode your returns.
