do you have a tutor or are you learning on your own? can you point me to resources you're using for piano learning for adults?
As for myself: I've started lessons about 6 months of trying on my own. The teacher's role is to point out the small things one does not even notice when learning on one's own -- and those can really make a huge difference. But in the end it is all about the learning process -- seeing what works for you at any given stage, filling the gaps, re-evaluating periodically if your approach should change. And it's a long-time project. Most people become comfortable after 10 years or so of daily practice. So either you're extremely committed/desperate/forced/enjoy the learning process with the long-term goal in mind, or you quit.
The specific resources I can recommend are:
- Lypur's video courses on youtube (both piano + music theory)
- "Piano Handbook" by Carl Humphries
- "All About Music Theory" by Mark Harrison
- http://www.musictheory.net
- Willi Schneider's "Klavierfibel"
