Well, you could have done that when you wrote the thread, as it should have appeared as an option near the preview and post buttons.

But, at any later time, the option to Highlight appear on the "More" drop down menu on the thread's initial post. Admins and discussions moderators can Un-highlight a thread at any time. Highlights will expire automatically after 7 days, but you can regenerate it again.

7 days are pretty much time to have this discussion get more users.
