Does it sting a little to be right, and not involved?

In my prior post, i described the probable outcome as dictated by Market Profile is ES (buying the bottom of the bell curve @ 1375.5, and then getting flat when the mkt trades up to 1380...the new center of value).  I also said that this was more of a gut call than a model generated trade (because the model had conflicting signals), and thus, I would not participate in the trade.  So, does it sting a bit when you have a gut call, and you don't do anything about it?  I'll say "Yeah, it stings little, but that is the price of discipline."
