What I meant by that is more "don't fight it", as in "don't let it dismay you, bring you stress, and don't judge the fact that it happens." That it happens is not a failure at all. It's normal. Just acknowledge and recenter.
When people first start meditating, they often find it very difficult to get a "quiet moment" and think that's a sign that they're doing something wrong or something isn't working. Neither of those things are true, and while you might get just a few seconds of "quiet" at first, as you practice more, that time will expand.
The basic point is that it's part of the normal progression (of anything, really). When you're doing anything new, you're going to suck at it at first and improve as you keep doing it. It's counterproductive to feel bad about the stage where you aren't good at it, and giving those judgemental feelings power can cause an unwarranted discouraging force.
