How to write an essay introduction that doesn't sound like everyone else's

Most essay introductions start with something broad and work toward the thesis. That's fine but it means every essay in the pile starts the same way.

What works better is starting closer to the actual argument. Not with "Throughout history, humans have..." but with the specific tension or question your essay is going to resolve. Drop the reader into the problem immediately and the thesis feels like a natural answer rather than a required box to check.

Shorter is also almost always better for introductions. Two or three sentences of setup, then the thesis. Anything longer and you're usually delaying the actual essay.
