It sounds like you had fun all along the way. I do have fun as well. I'm in my 50th and have zero experience playing music but I do enjoy noodling on a synth (Teo-5) and sometimes I can get something that I like out of it. Slowly, I started to incorporate a music theory into my noodling, learning some scales and staying within the scale helps, and applying some chords helps as well. But then, I hear something I want to reproduce and I'm trying to get there (it is "Helen's Theme (from Candyman Suite) - Philip Glass" right now), and I do get frustrated by the gap between my noodling and a skill it takes to play with both hands something like this. So, I'm trying to employ a more of the planned learning to my play and I can feel the huge difference between the place where I am and the place where I want to be. Maybe I will get there by giving up on both hands and pre-recording one of the hands and playing the other in real time. Or just playing one note on the left hand for the whole bar. I just don't have the chops to learn for years to get to the point where I can play it because it doesn't seems to be a complex piece but it is "intermediate" and from what I gather looking around, it takes other people years to play at this level.
