I enjoy having choices. Could I get by with much less? Absolutely. Do I have too much? Nope. Catching fish is only one of the things I like about bass fishing. I like the tackle, gear, conversation, and all the other pieces of the puzzle. If simply catching fish on one combo and a handful of lures works for you, enjoy. If having the price of a new vehicle (or several) in gear makes you happy, while having your financial house in order more power to you. Enough for me would not be enough for many. Not because I have everything I want, but because income limits my options. Buy what you can afford and enjoy the journey.
My wife used to think I had too much also. Now that she fishes with me regularly, she likes having options as well...
