Everyone will tell you something different. Getting to the piano as an adult is very hard and very different for different players.
Most people will tell you that having a teacher is best, which is true but only if the teacher is very good. COVID made that part easier (because now you can hire someone on the other side of the globe) and harder (because there's no thing like being in front of the same instrument).
In my opinion something is wrong in the way that piano is taught, causing even worse problems than the guitar. I don't know what the "right" solution is, but Phil Best claims he does, and has made an inexpensive (and admittedly very strange and very different) course around it. The course is available at https://playpianofluently.com/
I am exploring this thing (even done about 1/4 of it) and I am enjoying it very much and finding it effective and much easier than other approaches. Just FYI, I tried dozens and dozens of other things. Will it be good for you? I don't know. Will you enjoy it? Only if you are ready to "dump" everything you may expect out of a music class, such as exercises and learning music you have heard somewhere and thing you can play it. In a sense, this class is like you going to a running coach and saying "I want to run a marathon, can you teach me?" -- and he will respond: yes, but you have to become a pre-toddler again, start from crawling and relearn to walk. If you are ok with this attitude, the PPF course is a good fit, if not, don't even try.
Happy Easter to you and to all pianoclack addicts like me who cannot spare checking the site even on the very Holy Easter Sunday!!!
