I had my first lesson in 5 years today! After waiting 15 minutes on him to turn up, we got started. I set up and hit a few PW shots; every one was a shank 
Don't know why I was doing this. I don't normally, at least, not that frequently.
Anyway... it turns out I was standing too close to the ball, and my shoulders were open at address. After fixing these, the shank was gone! Never to be seen again. I hit some really good shots.
The pro kept commenting on how excellent my swing was! He couldn't believe that I wasn't playing off of single figures. 
He also asked me if I used to play off single figures in the past, and now just getting back into the game, but no, I play off ~17.
I went straight out on the course afterwords and hit my longest drive to date - carried at least 270 yards. Second hole - par 3, 118 yards - I hit a easy PW to within 4 feet of the hole and putted for birdie. Played quite well from there on.
I'm really trying to focus on keeping my head still throughout my backswing, before, I was dipping slightly and drifting a little to the right with my driver. I feel and look much better at address, and I'm looking forward to my next game!
