Shoot nothing but straight in shots half the length of the table. Use just the CB if you are a real beginner.
Diagonal Shot - CB below the side pocket to an OB near the corner.
If you can't shot it straight in, you will not be able to do angle shots.
Do that daily until the Videos show up.
The videos have progressive drills that get you into a regular, relaxed routine where you only have to think about your target line.
My suggestion for the OP to make the above (just doing straight in shots) so much better and so much more effective is that when practicing shots or drills, spend most of your time doing stop shots. Do stop shops at every distance from half a diamond to 9+ diamonds long (cue ball on the lip of one corner pocket, object ball on the lip of the diagonal corner pocket). Start with the shorter distances as they are much easier and work you way up as you begin to master them.
You also need to do all of these different distance stop shots at all possible speeds for each one. For example, for the stop shot at 3 diamonds distance, you need to be able to do it from the absolute slowest speed possible (which would be not much more than lag speed) to the highest speed possible (which will be 80% of break speed), and you need to be able to do the full speed range for each and every distance. Do not just get comfortable with only one certain speed for each stop shot but make sure you can do all stop shots at any speed because you will need that skill later to play various distances of position down the tangent line on cut shots.
While you are practicing the stop shots you need to be concentrating on two things. Your fundamentals (which is actually many things), and that the cue ball stops dead with as little possible movement in any direction (and the goal is NO movement whatsoever) and with no spin on the cue ball.
Doing the above is going to give you several things. You are going to have to focus on your fundamentals to really get good at stop shots at all distances, at all speeds for each distance, and where the cue ball doesn't move even the slightest bit after contact. It is going to help force you to develop and use good fundamentals and a good repeatable stroke.
Additionally, the stop shot is the single most important shot in pool by many miles, not just in and of itself, but also because every other shot is or can be based off of it. It is like the foundation for everything else. First, the tangent line is an easily and precisely identifiable cue ball path that you will use a LOT, and guess what, it is shot exactly as the stop shot would be except that you are only hitting only a portion of the object ball (since you are cutting it) instead of a full ball hit, but you hit it exactly the same. Not the mention that the stop shot itself is used a tremendous amount in pool, probably more than any other shot in pool, usually several times a game.
And for any shot where you know how to do a stop shot, you now have a good gauge or measuring stick with which to do draw or follow shots as you learn to judge and master them. If you need to draw the cue ball a little bit, then you know you have to hit the cue ball a little lower, or a little harder (or both) than you would for a stop shot. If you need to follow the cue ball forward for a significant distance then you know that you need to hit the cue ball much higher or much harder (or both) than would be required for the stop shot. It gives you a gauge to base all other shots on so that you will learn the feel of them much quicker if you have mastered stop shots at all speeds first, plus you are building your stroke and fundamentals and the basis of position play and everything else in the process of learning stop shots so it is like you are killing 20 birds with one stone.
You literally get almost everything developed (including focus and a billion other things I won't bother to list all out but suffice it to say there isn't much that isn't on the list) just be practicing and mastering stop shots. You will cut your learning curve down MASSIVELY and progress much faster into a good player if you will do this.
