No, for the little chips shots around the green and short pitch shots the ball should always be positioned near your right foot (assuming you're right handed). This doesn't always guarantee that you're not going to either hit it fat or thin but it's certainly going to help. Other things to look out for are:

1) Are you standing too close to the ball? Some people really crowd the ball at address but you've still got to give the club room to swing along a natural path otherwise you'll hit it fat or lift the club and hit it then.

2) Are you staying down on the shot? Like all other shots you've got to stay down through the impact zone otherwise there's a high chance that you catch it thin with far more noticeable results than a full shot.

3) As Ian mentioned, are you hitting down on the shor or trying to scoop the ball up? With a positive stroke downwards you can actually hit these shots quite hard and they'll bounce and grab on the green. With some practice and confidence you'll find that these shots aren't quite so delicate as you maybe first thought.

Hope this helps
