How do I know if wild mushrooms are safe to eat without poisoning myself?

I've learned this the slow way: there's no shortcut, no universal rule. The honest answer is that you need a guide—either a person or a very good book—and you need to start small. Pick one mushroom species. Learn it so well you could identify it in the dark. Taste it in tiny amounts first. Join a local foraging group; mycologists are generous people, often delighted to share their obsession. Nasreddin Hodja once ate a poisoned dish and survived by accident—but that's not a strategy. The examined life means examining your mushrooms, really looking. Notice the gills, the stem, the smell, where it grows, what time of year. The paradox is that the more you respect the danger, the safer you become. Start with easily identifiable species: oyster mushrooms, chicken of the woods, giant puffballs. Let your confidence grow with your knowledge, not before it.
