Hi. Feel free to disregard my input because I'm new as well but I've been taking lessons with a former pro and he's helped me a lot with my swing.
Before I went to my first lesson, I read as much as I could and watched as many videos as I could about swing sequence. Then I would try out what I read and it didn't feel good and my ball didn't go where I wanted, if in the air at all.
My teacher's greatest insight so far that really resonated well and helped my swing A LOT: achieve proper address then just swing the grip. (that's the condensed version)
Basically, your lower body will naturally do what it needs to do. All the stuff we have read about swing sequence is correct, but not everything necessarily applies to each of us individually. So in my first few lessons and practice sessions, I tried to think of all the steps I've read and do them per what I've read. That messed me up a lot. First of all, our total swing happens too fast to try and think about all those things then actually do them. Also, during the swings in which I tried to "properly" shift weight and rotate my hips, etc., my teacher would comment that I had too much unnecessary movement in my lower body.
So when I cleared my mind and literally just swung the grip (important to swing the grip instead of trying to swing the clubhead), my lower body reacted to the movement of my upper body and arms, I kept my backswing smooth and controlled and the results were great. On my good hits/swings, I recall that it feels effortless and easy.
I really recommend taking some lessons so you can get specific advice and help on your swing. And also, the instructor can customize all the tips we read to what works for you personally.
Hope I helped, sorry if I didn't!
