Dakota Cues, at the risk of repeating myself, drills are great if you are already aware of possible position defects, and more importantly, how to correct them yourself. If you don't, the drills will hurt your game bad, as you will train your mind and your body to play wrong: sure, your game will improve, but you'll peak and then you won't know why you can't play better.
At that point, you'll have two options: either you'll research yourself what's wrong with your way of playing, which requires honesty with yourself, time and some understanding of body mechanics, or you'll get an instructor to help you out. Either way, you'll have spent money and time training for nothing, you'll spend more time and more money deconstructing your crooked way of playing to rebuild it right, and you'll likely need an instructor anyway.
So, unless you're very VERY sure you know how your body should be positioned for correct play, and how to position yourself, and what to look for before shooting to fine tune your aim and check your stroke, don't pass up an opportunity to spend a couple of hours with a good instructor. Again, you'll save yourself years of frustration.
I myself was lucky enough to have things explained to me by an exceptional carom teacher when I was a teenager: he was a physics professor at the local University who had researched billiard physics and body mechanics, and he was crazy enough for the game that he actually made a carom simulator game for DOS. He took the time to explain how things work, and helped me develop my very own, personalized routine to get in stroke. 25 years later, I still go back to the basics he taught me whenever my level of play decreases, and that is what I teach my beginner students. But there is no way to teach this over the internet. You really do need someone to help you out at the table, unless you already know your fundamentals.
Save yourself years of frustration and wasted money, and do talk to an instructor. If an instructor gets on your nerves, seek another one. You're bound to find one that you feel good with. Even if you spend $500 finding a rare pearl of a teacher such as mine, it's nothing compared to thousands of wasted hours playing incorrectly, feeling annoyed at yourself, and paying the poolhouse owner by the hour.
