Ball position changes with each club; use the time you spread your legs under your shoulders during your set up routine to position the ball correctly
If you tend to come up out of your stance and hit thin shots you can not only fix that but also increase your clubhead speed with this easy drill using a block of wood to place your toes on
A common fault in the set up is having your head down and chin too close to your chest, this drill will fix that and allow you to turn effectively and use your legs correctly in the swing
