I suppose for me there have been times I wondered what to do but not often. I'm a tackle junky and I have no problem putting It on the peg board and during the coldest of months I organize, reorganize, and simply enjoy looking at what I have worked my tail off for.
It's a personal choice as to whether you want to sell or give away but for me I almost always give baits away. In the end enjoy what you have, use what you have confidence In, and have fun fishing and collecting.
