I’m planning to buy a keyboard this week. I’ve always wanted to learn piano since I was a kid but I had no chance. I’m hoping that its still not too late for me to learn. I have no plans of hiring a teacher, I want to try learning on my own.
Your never to old to learn how to play 
. Have you considered going down to your local community college and taking a beginning piano class? There is only so much you can learn by yourself and a teacher will help you build the proper foundation so you can learn how to play properly.
