Sometimes you have to push to get the answers you need.
The word "just" bridges a multitude of gaps. As in "just lose weight!", "just be confident in yourself!" and "just stop taking heroin!". It has that handy ability to make something difficult sound as if it should be easy, with the bonus implication that anyone who doesn't find it easy should be a bit ashamed of themselves.
