Pull your head out of your ass

Something you say to someone when they need to stop procrastinating and/or willfully ignoring problems around them that need to be solved. When someone is willfully slacking off, this is a great term to use. When someone has their head in their ass, it means they're intentionally avoiding the subject of problems that need to be fixed, or they're intentionally making themselves ignorant of a problem. People do this because they think the problem may just disappear, but it never will, that's just life. You have to confront your troubles, not ignore them.
