Take lessons with a piano teacher and practice a lot on your own.
I relate to that: I was inflicted a couple years of piano lessons as a kid, and hated every minute of it - because I detested the music that my teacher and my family considered appropriate.
40 years later, I stumble on electronic musics and realize I would enjoy making some - and I joyfully (and incompetently) began on that path, lately becoming ripe for some dry theory because I now value it.
Each person is different though: my daughter always enjoyed the technical exercises for their own sake !
