I suppose, if it is considered a skill, mine would be "Patience" I have many times been on a dry run where every hand seems to have a Deuce in it 7/2, or A/2, etc I once made a remark to a dealer "have you got 30 Deuces in this deck? I seem to get one every hand" but I always say it with a smile on my face. Being card dead for long periods is annoying, but it happen's and you have to suffer it.
I used to go fishing when I was younger and spent many hours waiting on the riverside, for a bite, hoping to reel in a big one, Now I hope to reel in a Whale or Shark! (lol)
When the fun Stops, STOP!
