Ok, back home, bigger screen so I was able to read this easier. I got my license in 1989, flew for a few years and stopped with about 175 hours due mainly to new kids. Now they are all growed up… and I have been here on POA for a while and watching aviation youtube videos. So last summer I decided to make the leap, I needed the medical which was a little more complicated than 25+ years ago, but in October I got it. I had started flying last July and my experience with the flying part pretty much paralleled yours. Take offs, easy, took a little bit to hold altitude and course, but it came relatively easily, stalls? no real issues there, landing? yeah, that took a while, but I had a while waiting for my medical so it wasn't a big deal. Being comfortable, that was my biggest issue, my instructor told me I was ready to solo again before I got my medical ( no, he wasn't going to let me do it without the medical), but I didn't feel ready, so I kept flying with him and working on stuff. Medical came and I soloed.
Here's what I learned during that experience: I expected perfection out of myself quickly, but realistically it had been over 25 years since I piloted a plane, I was very rusty. My instructor was great, very patient and got me to where I needed to be. But I learned that perfection took time, and no one really attains it all the time. Safe and proficient are key. Before my solo, I told my instructor I keep screwing up things, like my landings, bouncing, a little off centerline, things like that. Not unsafe but annoying to me. He told me, yeah, I know that, but you correct your mistakes when you make them and you are proficient and safe, every thing will get better as you fly. At that moment I lowered my bar a little, I was ok with a little bounce on landing, eventually I figured it out and that happens very rarely now. A little off centerline, nbd, work on it for the next landing. My flying improved quickly when I accepted things may not be perfect and that a little less than perfection (not too much less) is ok. Safe and proficient is where it is at.
At the end of it, it took me about 25 hours or so to get to where I needed to be. I was probably ready at 18 to 20 hours, but I was in no rush. So the AOPA estimate of 1 hour instruction for each year was pretty accurate for me. In my training I wanted to be at the point where I could plan a trip to an airport I had never been, fly there land, do what I wanted to do, then fly home without sweating it. I'm there. There are guys who can lay off for long periods of times and come back in 3 hours of instruction, or so they say, but I'm not one of them and I'm ok with that.
Now I am flying a Cirrus SR 20, working on my Instrument rating, when that is done I will probably pull the trigger and buy something if I can't find a rental situation that fits what I want to do, which is long cross countries.
So my advice is be patient, fly, the more you fly the easier it will get. Don't worry about the hours it takes to get proficient, that is an unimportant criteria in my opinion, unless your instructor is a chump, but you should be able to gauge that easily. Just make sure you are comfortable flying the plane when you are done and you know stuff like how to get a tie down, deal with ATC or pump gas into the plane when you are done.
One final thing, back when I was a youngster I used to worry about talking to my instructor about mistakes I made, not sure why, he was a great guy. Now I don't give a crap, I talk about things that happened and learn a lot from them when I am with an instructor. I've set a personal goal for myself to fly with an instructor every 6 months after I get my IR, and more if the need arises. I guess I've grown up too.
Best of luck in your training, be patient with yourself, relax and have fun.
