I too started on piano at around 7 and moved to guitar at 14. I soon dropped piano lessons and continued self taught on guitar.

I would suggest spending the time to find a local piano teacher and work with them for a time..... for the length of time you need to accomplish what you really seek. A piano teacher will get you up and running and help you avoid the mistakes and things that will bog you down, simply because you may not know better.

Find one who will work with you on reading as well as playing by ear. Some refuse to accept playing by ear as legitimate. Avoid them. Commit to one year and see where you are in a year.

A teacher keeps you moving and learning by requiring you to practice and learn things for the next lesson. Accountability.

My teacher leaned towards reading and classical stuff but also made room for the pop music of the day as long as I had the sheet music for it. She also did encourage playing by ear as long as you could read as well. She taught me a lot about theory.... something few would ever learn on their own and theory is very valuable.

Have fun.

You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
