When I was learning, my bass fishing success was very, very minimal at first. But it exploded once I started doing three things:
1) I studied up on bass seasonal behavior -- what are they doing, where, and why, depending on the time of year
2) I stopped worrying about WHAT bait I was using, and starting paying more attention to WHERE I was using it -- location, depth, cover types, structural features.
3) I learned how to fish a plastic worm on a texas rig -- how to be patient, select my casts carefully, feel the bottom, feel obstructions, detect strikes, proper hooksetting technique. I use all kinds of lures, but becoming good with a plastic worm made me better with everything else.
