Congrats nice trade.
Definitly the execption. I have known some very good option traders that will have a year or maybe even two with trades like that only to have it all evaporate through commissions and spreads trying to get out of trouble, ie. sell puts. One guy even tried (not trading) unless volitility was there so he could overcome the spreads and commissions. Maybe once you get up to a few thousand contracts a year you might be able to balance things out. Not for me.
