Fish always change what they want, moody like women. Of course, this is also a good thing because if you could throw the same presentation all the time and catch fish, fishing would be plain boring. But it can be hard to build confidence in lures when fish hit them for 1 or 2 days, then they don't and you're left wondering why, and being limited to bank fishing and a very very small selection of tackle doesn't help in my situation. Sometimes I wish I could just tie on the lure that always works, toss it in, and reel in fish, but that is a longshot.
