Never complain, never explain. And what it means is, don't complain about life. Don't explain what you're doing or why you're doing it. Just do it. By whining and complaining, all you're doing is making people think bad things about you, looking weak. And when you complain a lot, you, you have a mindset where everything is kind of a potential complaint. Stop whining, and stop explaining yourself, and just do things in the world, and let your actions speak for themselves.
