If you intend to do something, you mean to do it or have it in mind as a goal. Do you plan on getting your holiday cards in the mail before February this year? Then you intend on getting them out early.
The world is full of good intentions, meaning there are lots of people who intend to be nice, eat better, floss more, or pick up their dirty socks. But things don't always go as planned. Your actions could produce results that you didn't expect, specify, or ever intend — that might explain the well-known proverb, "The road to Hell is paved with good intentions."
