Make no mistake about it: the choices we make today can greatly affect our future. I stopped at my favorite Mexican restaurant for a salmon burrito, and while walking back to my place, I ran into my friend Jeannette, who asked me if I wanted to get some lunch. I declined, since I had already bought it, but should have taken her up on her offer: I got food poisoning from the salmon, and spent the rest of the evening throwing up. Ugh.
