A bumbling fisherman is "all talk" as he attempts to catch fish in all the wrong places. A good correlation can be made when fishing for men... you've got to go to where the "fish" are. Evangelism is meant for the non-churched. We can't sit contently in church and expect those who need Christ to come to us. Sometimes we've got to go beyond our typical routine, go out of our comfort zone, go to where the unsaved are. Go into all the world. We're all gifted differently, and should serve Christ according to the talents and strengths He's given us. Just because we like to teach (or fish) doesn't mean we're good at it.
