Well I had a few over the years, but being taught how to read music as a child and having the oppertunity at home to play it. (My mom had a baby grand piano in the house until I was 11 - then repurchased one a few years later and I played then. I was the only one in the family other than my mother who could, or cared to.)

I'm not good at it, but it's something that when I'm really upset I can pour my heart an soul into it and it's theraputic. I play for myself, to get lost in that 'zone'. Sounds creepy, I'm sure.
