Ive heard and seen some great research on this by James Altuscher about cutting that down substantially by training yourself to learn quicker, i.e. through diet, nutrition, accessing flow, and other biohacks.,

Turns out the 10,000 hours aligns with what apprenticeship was in the trades, roughly 7 years.
Thanks for the great read
