Dont go crazy buying a bunch of different lures...Pick things up here and there depending on the type of water you fish. You will learn what you are comfortable with and good at......My lakes and ponds are shallow and have a lot of weeds so, i dont use crankbaits....Spinnerbaits work well for me (I use War eagle brand) , lots of texas rigged soft plastics, jigs and topwater baits. Those are the things that work for me in my waters.
All im saying is, dont set out to have everything all at once because you dont need to ...Just go out and fish and have fun and you will accumulate what you need over time as you learn your waters
