I asked this question because I don't think there is really "one thing". I have tried over and over in moments of reflection on how and why certain things have or not happened while involved in my favorite recreational activity.
If I had to list the top three though it would be :
a. Confidence in your ability and what you know.
b. Experience you have have had in many differing fishing situations.
c. The determination to succeed, as in life in general, you won't succeed unless you will yourself to do so.
Thanks for all your input and answers, tight lines and many fish in your season ahead.
