Try using the eight ball instead of the cue ball. Position the
middle of the number eight upright and exactly where you are
attempting to hit the cue ball. Then look at the chalk mark on
the eight ball, especially when you miss the shot, and that will
tell you if you are hitting the "cue" ball where you intend to.
If you are not, you must work on that first. But even if you do
hit that mark (almost) exactly in the center, then there are
other things, like steering the cue ball, that could be causing you
to miss.
Let us know how the results of the eight ball tests.
