You have to believe you can do it. Without this belief all is lost.

Good attitude is easier to maintain if you are sharing this journey with other people. You can meet other adult piano students at professional piano recitals. Strike up a conversation with the person sitting beside you. Chances are good that only pianists and former pianists attend piano recitals.
Attending concerts is a great way to keep our desire alive. Becoming part of a "scene" as an insider allows us to interact with others who share our musical passion. We'll meet others on the same journey. Some further down the road, others just starting out.
Tonight we saw Jo Bonamassa at Roy Thompson Hall Toronto. Rockin' good fun. Twenty five hundred enthusiastic middle aged guitar fans, most of whom I'd guess, played the guitar to some degree.
I'm looking forward to practice tomorrow.
You've got to learn your instrument. Then, you practice, practice, practice. And then, when you finally get up there on the bandstand, forget all that and just wail.
I'm a professional pianist and music educator in West Toronto Ontario. I'm also a devoted student and teacher of the drums.
