You can hunt from the ground and be just as sucessful as any other hunting method. Just from the ground you cant see through things as good as you can see above them in a tree. Pay attention to the wind direction and cover your scent really well and you ought to be in good shape. For me blinds have scared deer away more than when I'm tucked away in good cover. If they just see a blind for the first time without either being used to seeing it there or having it brushed in and a part of the woods they will usually spook quickly so cover well.
