Yeah, roughly 2 ~ 4 years. Call it 3. That's how I tend to think about skill acquisition.

Just personal experience of getting good at things over the years. It's a rough model and I'm happy for people to disagree if they want but the numbers aren't hard and fast they're more of a ballpark hueristic.

It's sort of a 4-tier order-of-magnitude pattern I suppose.

X0 hours (low hanging fruit)

X00 hours (pain period)

X000 hours (personal mastery)

X0,000 hours (world-class mastery)
