Can you even train artistic talent? Doesn't it require a natural gift that you're born with?(musician/artist here) I don't believe in 'talent' or 'gifts', and I don't believe art/music, like a lot of things, is something you can teach (mostly). You can learn it, but you can't teach it. (Botvinnik - founder of the 'Russian School of Chess' (!) - said that about chess, I keep seeing people in different fields saying that.)
You learn it by doing it. A lot. And learning from what you love, e.g. the greats in your field. And you won't do that day after day for decades unless you really love doing it. No-one else knows what you should be working on, or what you love. Everyone's bad at anything when they start. I hear a lot of people saying they wished they played flute (or something), but they're not talented. That myth does a lot of harm. I tell them, well, just start!. It's all anyone can do. Art is essentially about doing your own thing, not willfully, but following what your nature dictates. 'You' don't create it; it just flows out of you.
So I'd also think that space travel training is more teachable than art, for different reasons.
A (probably apocryphal) story: ...a woman once came up to Fritz Kreisler after one of his concerts and said to him, “I’d give my life to play as beautifully as you do.” To which Kreisler replied, “I did.”
One's own path. - If we take the decisive step and enter upon the path which is called our 'own path', a secret is suddenly revealed to us: all those who have hitherto been our friends and familiars have imagined themselves superior to us, and are now offended. The best of them are lenient with us and wait patiently for us soon to find our way back to the 'right path' - they know, it seems, what the right path is... - Nietzsche, Daybreak, 484
