I had the same questions as Dreamer. Why would you sell a keyboard just because you do not have the time to play it? Why would you get another keyboard, did your circumstance change?

Here is where I am heading. I think that maybe music is a light hobby for you to the extent you thought you can sacrifice your keyboard. After selling it, you realised that you loved playing keyboards more than you first thought and now you are confused. Confused about if you should pursue playing music and how expensive of a keyboard you need to buy.

Am I capturing your feelings correctly?
