Hey Rob, welcome aboard. As someone who's quit guitar more times than I can count, I feel confident in warning you that approaching guitar as a "breakneck" sprint will almost certainly result in a lot of bad habits, mounting frustration, and ultimately just another episode of throwing in the towel. Everyone here wants to learn as much as possible as fast as possible. Fortunately, most have learned to see this instead as an enjoyable unending jog through the park. In the end, that approach will get you to where you're going much faster, even if it seems excruciatingly slow at first. I suggest you start with Guitar Fundamentals 1 & 2, and don't rush it. Best of luck in your journey.
