Confidence is Paramount!
If there is even an inkling of skunk feel in your mind you will most likely be skunked.
One thing I like to do while fishing:
When I get a bite I casually tell myself "thats cooo. wont be the last bite of the day. Good times-keep on keepin on *whistles*" -you know, something like that.
If you pressure youreself, its just as bad as the idea of the skunk creeping into your mind IMO.
If you plan, research and gear up as best you can, it totaly helps the "get the job done" mindset and boosts you happies.
