I tend to put Overconfidence on my character sheets to remind me to take risks and be 'heroic'. Back in 3e when it was worth 10 points (which now means you have a control roll of 6-, which is pretty painful), it was a no-brainer, because back then I tended to play that way be default, so for me it was nearly free points.

As a GM, I've put it on a number of NPC sheets for friendly NPCs because the players tend to be over-cautious, and this gives a voice to the bolder options (which with luck the Impulsive PCs might pick up and run with before the cautious PCs/players slow everything down again).
