Most important skill for the Weekend Warrior

In the spirit of excellent discussions we have had right here just lately I will pose a issue to the board. I was just getting this dialogue with John Rodgers as we have been speaking about how we used to fish 10x more than we do now. The question is, and this is for the weekend guys as it is a lil distinct for the charter boys. WHAT IS THE MOST Critical Skill to boost the fish you put in your box???? Lets hear some responses and I will chime in with what I assume is the number 1 skill to grasp.
