I can think of two bass, but I don't know if they changed my life or not.
First one happened when I was around 9 or 10. Dad was getting the boat ready and I was casting a Rebel jointed minnow. I was bringing the bait back in and the rod loaded with some weight. I pulled back to set the hook, and the bass jumped. I couldn't tell how big it was, but it threw my broken minnow. Until then, I didn't know they could do that.
Second one happened when I was around 15, and we were catfishing in a 3 or so acre pond. We were fishing with dough bait on the bottom. The pond was clear and shallow so you could see when the fish took the bait. I had a cat messing with the bait, I see a flash under the water, and my line starts moving off. I landed a bass that weighed about a pound.
