I have a three year old daughter. In her three years of life, I have recorded hours and hours of high quality audio of her. I've also encouraged her to bang on keyboards and drum pads and guitars, and recorded all of that, as well. I then took that material and chopped it, mutilated it, sequenced and mixed it, and released two albums of what I'm calling "classic industrial music", all under a pretend band name, with the credited musicians being my daughter, and our teenaged dog, who is also featured on many of the recordings.

Naturally, I then released these two albums to the world, where they have sold roughly 0 copies. This doesn't bother me, though; that was never the point. It is, in essence, a long-term elaborate "performance art" piece, that is intended for my own amusement, and possibly my daughter's amusement, once she gets old enough to "get" the joke. In the immediate time, I get value out of seeing her enjoy playing instruments and making sounds. And I'm giving her the experience of making music, in whatever way she sees fit, before she ever gets taught a bunch of nonsense about what ways are OK and not OK to make music through more formal training.

Any project that naturally holds your interest, is probably worth pursuing, regardless of the overall value to humanity. At least for a little bit. Because you're generally going to walk away with knowledge you didn't have prior to starting it, and benefits you wouldn't have predicted had you not gone down the path at all.

Oh yeah, also; don't take advice from me. I make horrible choices, then I commit to them.
