Howdy and welcome.
With no other information to go on, I'd say you need to focus on a small handful of lures. Those lures I think would perhaps change depending on location, but would be safe to say these are core lures everywhere.
-Squarebill crankbaits that dive to about 5' in colors gold or shad
-5" Senko worms with or without a bullet weight in colors green pumpkin and whatever else suits you
-Zoom finesse worms and Trick worms in colors white, watermelon red, green pumpkin. I'd rig this weightless, or with a split shot rig.
-Rebel pop R for a topwater
-3/8oz white or white/chartreuse spinnerbait, double willow in spring/summer/fall
For me, those would be solid go to lures for just about anywhere, and I think most here would be able to do well with them also.
My secret lure, though, is a bit uncommon, but is widely available. Zoom fat albert grubs in green pumpkin. But instead of rigging it on a jig head that is common for grubs, I texas rig it. I usually use a 2/0 gamakasu extra wide gap hook with a 1/16 oz bullet weight. It is something the fish doesn't see a lot rigged this way, and I use it in place of the popular ned rig.
I would limit my tackle selection to those, or no more than 1 more, and I would focus on shallow water areas where they would work. Master these, then move on to other lures, other depths, and new techniques.
