Making great progress following lesson

I have watched Tom's videos on YouTube for about two months before finally joining the golf school and beginning to overhaul my swing. After spending quite some time trying to get the 3 body motions down I decided to get a V1 lesson with Tom since I was struggling immensely to make any kind of contact at all and showed no progress even with short swings. I sent my videos last Friday and got them on Tuesday but was playing a round that day and did not want to have a lot of swing thoughts, so I waited to view the lesson. I ended up shooting a 115 that day and went straight for the lesson and drills. As Tom mentioned in the lesson my takeaway is so far on the inside and comes back under the plane so I see a lot of topped shots and hooks. It never occurred to me that the swing could go so wrong just in the takeaway and make it feel like I have never touched a club before. I began working on the drills for the next few days and played a round today shooting 87, my lowest score ever on 18 holes. I don't hit very far so my course management came into play by avoiding hero shots and even playing par 4s as par 5s sometimes just to make sure I was taking out the big number on the hole. My contact was great today and gave me a lot of confidence over the ball on each shot, something I haven't felt in a long time. I've still got a lot more work on my swing to get the consistent contact I am looking for, but it feels great to enjoy playing and hitting well for the first time in a while which was made possible by taking the lesson and working on the drills.
